Hello,
Switcheroo plugin is great - that's almosts exactly what I was mainly looking for when trying different launchers. Following is of course just a proposal and I'm aware that it might not be the most popular usecase or user's excectation ...though, I think it is and that's why I'd like to discuss it.
In my opinion in case of switching opened windows, user is mainly intereset in application name and not title of the window. For example, when trying to switch to the browser, this plugin focuses on the window title mostly - being title of currently focused tab. In my case, I don't exactly remember what page I was browsing and I just want to switch to the browser quickly.
There are, of course, opposite situations - e.g. when you have ten different windows of Windows Explorer opened and you want to switch to specific folder. I think, thought, that it still would be possible taking my suggestion into account - application name would be just more prefered.
I would also like to sugggest filping app name with windows title visually - to be consistent with that way of thinking.
One more time, this is just a humble idea - I would love to hear your thoughts, though.
