Fixable UI problems:
- Keyboard: Put a period on the alphabet page. This is useful mostly for web pages but also for books/authors with periods in the name. Just shorten the spacebar a little to make room. And keep it in the same place (next to the spacebar) on the other pages. (side note: why doesn't the number page have a link to the accented letter page?)
- Sudoku: you can add small, "note" numbers in any order you choose to type them. But you have to "backspace" to remove them, and only in the reverse of the order you put them in. It would be better for the buttons to simply toggle the number, i.e. turning them off should work exactly the same way as turning them on currently does.
- Foot/end notes on standard epubs should work as foot/end notes do in kepubs, i.e. with a pop-up overlay. Many epubs don't have a proper return links, making them a chore to read if the notes are at all useful.

Tasty, tasty, gravy:
- Replace the fairly useless sketchpad with a text-based notepad. Better yet, combine the two: text entry with the ability to scribble on top.
- Go the extra mile typography-wise. You're already doing a very decent job here, but I've noticed a few bugs (e.g. I get line breaks on the inside of brackets/parentheses and around en dashes; this shouldn't happen) that could be fixed. And I'd also like to see those little details that add real finesse to typography. For example, punctuation at the beginnings and ends of lines (! and ? excepted) should actually hang over the margin so that a letter is at the margin instead.

Thanks for the great work, Team Kobo!
