I personally type a lot, and one thing I'd love to be able to use with the 3 whole function layers Wootility gives me is to put in things like letters with accents, such as é.
I looked around and couldn't personally find anything that would let me type in even common characters such as that.
That's why I suggest, just so it doesn't happen to anyone else, that you can put in any character into your keyboard database.
Letters with accents, symbols, and even ascii characters would be welcome!
I'd see this opening up tons of options for everyone, such as not even needing to remember what alt+numpad combinations to type in your favorite characters.
Please consider this! It'd help me out so much, and doubtless it'd help others as well!
