rpn-30's Issues

Clear the registers

A long hold on CLR when everything else is already clear could clear the registers 0-9 (or 0-8 if 9 is the iOS clipboard).

Recall register hides decimals

When a register is recalled (with chord RECALL [register], the value in the register is displayed without decimal places. The value is maintained with decimal places but the decimal places do not show.

Example
Keystroke sequence: 1.2345 [STORE 3] CLR [RECALL 3]

Display: 1

Additional keystroke: ENTER

Display: 1.2345

I'll try to look at the code later today.

Schematic for "Build Your Own Keypad"

Here is a rough sketch of how Build-Your-Own-Keypad might work:
https://photos.app.goo.gl/ABwLv5a9dvN56vuB9.

Users would see the 9-digits of the keypad with their current long-tap functions (on the left) and they would see a library of available functions (on the right, maybe grouped by math category). User would tap and drag a function to a keypad button, replacing the current long-tap function with the new one.

There should probably be a draggable "no function" or "blank" option.

We might or might not want to protect people against assigning the same function to two keys. If a function that is already assigned to a key is dragged to a new key, then both keys should be updated (leaving the previous assignment blank and ready).

This is way over my head in terms of Swift programming; I don't know very much about writing GUI. Would you be interested in presenting it as a hackathon challenge? There may be IT students at UMass or elsewhere who would have fun writing something like this as practice in Swift.

Decimal point while entering a number

When entering a number the decimal point does not display until the number after the decimal point is entered.

Suggestion on Store/Recall to/from iOS clipboard

Would it be easy to make store-9 write to the iOS clipboard and recall-9 read from the iOS clipboard?

Losing one register in exchange for clipboard access seems like a good trade-off.

Here is an explanation of clipboard access in Swift:

Thanks for your consideration.
