Flutter imageboard browser for iOS and Android

chan's Issues

Rewrite Saved Attachments

• Saved attachments page is really bad in two-pane layout
• Saved attachments are not reliably saved (still sometimes dependent on ExtendedNetworkImage.cache)
• Saved attachments should be shown in Files.app if possible
• It needs to have its own identity compared with the "Download" button

Memeflags option when posting on relevant boards

Haptic feedback should be used more in the interface

For example, when opening or closing replies, peeking at HoverPopup.

Improve startup animation

Would be improved by #1, but separately from absolute time, there are some frame drops in the spinner animation on the current versions.

Tapping in the margin of an OverscrollModalPage should only continuously pop as long as that tap is in margin on below pages

It will make it easier to navigate reply trees where there are a lot of replies in the middle of the tree.

Thread row layout doesn't match post row layout

It could be an opportunity for optimization, there is a lot of duplicated code. Post row is not as customizable as thread row at the moment.

Licenses page is bugged since the MasterDetail page is nested

Very insignificant

Button to cache all images in gallery

To avoid loading spinners or maybe for offline use?

EdgeInsets should be differentiated based on hardware vs software obstructions

Landscape mode on iPhone X+ looks bad as there is dead space on the side without the notch.

Some performance issues seen on iPhone XR

Not sure if it's the iPhone throttling as they don't seem to be observed when attached in profile mode. It could have to do with the power being connected.

Send to phone from desktop

Different than #11 as this would be some sort of userscript (Chance not running on desktop).

Push notifications

Allow browsing cyclic replies if the graph is large

Right now you aren't allowed to open replies which are already opened as a parent of the current reply. It makes sense if the reply tree is simple, but if it's complex, you might want to open ancestor replies.

Reduce memory usage

It's not crazy high but still a lot higher than it should be. The app is evicted more often than it needs to be. Would be helped by fixing #1.

Thread scrolling jumps when switching apps on iPad

Seems like the viewport is changing sizes after alt-tab (could have to do with the capture of the screenshots for multitasking resize). Maybe we can detect and recover from this, it only seems to happen when scrolled all the way to the bottom.

In-app way to switch between multiple provisioned sites

Will be needed after #31

Play WEBMs while converting

Long WEBMs can have unacceptable load times. Maybe the playback could begin early by partially reading the output file.
Issue is that the mp4 MOOV atom is not computed until the end of transcoding.
Would be useful if #19 is not solvable

Search page is useless for default site

Maybe it should be disabled?

Sync settings and data between devices

Way to select text with mouse

Mouse shouldn't be able to drag the interface around. Then it could be used to select text without opening the "select text" popup.

The background reply in PostsPage only expands from the top down

When dragging up, the post should expand from the bottom up. This was assumed to need an upstream change to TextOverflowPosition, but maybe with the new use of Column` to render posts it would be easier.

Localization

Optimize embed requests

Some sites are on the embeddable list, but they don't ever seem to return an appropriate image, so don't end up being shown. Removing them from the embed list (patching it) will mean reduced network requests and no loading embed widget which disappears once it's realized the site shouldn't be embedded.

Framedrops opening and closing thread page

Add to F-Droid

Will need to set up a relatively clean build script.
Right now blocked as some android dependencies don't build in current flutter/master without some patches.

The background reply in PostsPage should fade in

Right now, the background reply instantly appears behind the posts when scrolling stops. But if the user starts over-scrolling before it comes to a complete stop, it's not shown as expected. The duration of scroll-in should be known, so a fade-in could be used instead.

Add option to share as image

Export a clean image of a post or thread for sharing to other apps, rather than linking to the post or taking a screenshot.

Fake-insert new reply into thread

Sometimes it takes some time before new thread data is provided by the sever. Once the reply ID is known, it could be inserted into the thread data and shown. The app would appear to be faster.

Automatic cleanup of thread history, image caches, etc

Right now that stuff just builds up forever, it's not obvious that it should be cleared semi frequently.

Show number of pinned (from filter) threads on board tabs

Right now the "red" count isn't used for board tabs. This could be a data point to add. Although on two-pane layout there are really no "board tabs" so it would be useless there.

Add support for more chans

Add flag filter to search query

Would need to determine which flags are possible based on board. Maybe related to #27

Huge images show up as black rectangles on some devices

It has to do with the Skia graphics cache size. Not sure how much of a good idea it would be to unilaterally increase it.

Create builds for Windows, macOS (Intel), and Linux

Need a way to show WEBMs. Could use dart_vlc but appears to crash upon minimal testing.

The overscroll pop should complete faster based on scroll velocity

Right now, it always takes a fixed amount of time to fade-out an overscroll popup.

Syntax should be highlighted in the post form

It would be good to verify that uses of [spoiler], [code], and [math] were well-formed before posting.

Some way to load MD5 block lists

Loading premade 50,000+ line block lists is not possible right now. Will need a way to open as file, copy to internal directory, and load in an efficient manner.

WEBMs loading slowly on iPad

For some reason WEBMs load awfully slowly for no apparent reason. Most devices they load very quickly. FFMPEG logs appear normal.

Rethink of saved threads vs watched threads

Saved threads might need to be split. One part would be the notification of new posts (#23) and the other would be a sort of bookmarks system. Then maybe posts, threads, and attachments could be organized together (#13)?

Use translucency for navigation bar and tab bar

More complex than it seems due to how the replybox and tabs list hide behind the tab bar.

New page or option to scroll (non-paged) vertically through gallery

It's not easy to scroll through the gallery quickly in high-resolution right now.

Simultaneous multi-board archive search

Could be done by selecting archive first (limited to subset of boards on that archive) or a fusion of multiple searches behind the scenes.

persistence.dart should be rewritten

Right now all previously seen threads will be loaded into RAM forever. The correct behavior should be to only load into memory when needed.

Last seen post ID is modified during in-thread search

It's not really representative of the amount of scrolling that has occured, maybe updating that field should be blocked during search.

Top of images in gallery is blocked by notch

Will need to update extended_image upstream to have some sort of concept of padding within the image rectangle

Should be able to paste image in the reply form to attach it

Dependent on Flutter support. Would be a large feature to add there.

Set a limit on the number of WEBMs transcoding at once

Starting too many WEBM transcoding sessions at once will probably crash the device.
With hardware transcoding I believe it throws an error when too many are added, so it is not fatal.
The queue would need to reorder, it would be unacceptable to have to load all preceding WEBMs before the final ones.
Could be an issue for #21

Chunk / page system for stickies

Integrate with archives to fetch blocks of 1000 posts for event stickies.

Improve responsiveness of gestures

In many places some hacks with touchSlop are used to handle gesture priority.
Maybe Drag start vs accepted could be investigated. Or fix upstream: flutter/flutter#11384

Running on the desktop creates a lot of folders in the Documents directory

It's due to the use of getApplicationDocumentsDirectory()
