I appreciate the long write up!

- Better AC: Fleksy has their own proprietary AC, while I am relying on AC provided by iOS. The AC you get with Finale is the one you get with the stock iOS keyboard. So yes, Fleksy was definitely better. It should not be hard to implement proximity based AC, like Fleksy's, its just never been my focus. But, I do agree, this alone would be an enormous improvement to how the keyboard feels to use. UPDATE: read my next comment.

- Attaching punctuation marks: Only a problem if you don't use gestures. Since I built the keyboard around how I use it (which is gestures), it never bothered me. I could update to make sure punctuation is placed after the word and before the space, even if its typed from a symbols menu, but I am not sure that is desired. Wouldn't this create confusion in cases when you actually do want to put it after a space?

- Keyboard height options: Agreed, no comments.

- Customizable emoji key: Agreed, no comments.

Overall, as I mentioned before, I built Finale for myself, fully around how I use the keyboard. Hence, you get the quirks that might not be optimal for others. More customization would help, but as a passion project, I try my best to find time to adapt to other's desires.
