Very customizable (I like having number row always visible, and having long press for symbols on each letter).
Has gif support built in.
My biggest pain point is:
It auto corrects words that are spelled correctly to other words. I type "our" and it changes to "out", I recently typed "purpose" and it changed it to "purple". Autocorrect is awesome and necessary, but I hate that it corrects words to other words and not just typos. I wish I could find a keyboard that has the things I like without this annoyance.
That seems interesting, but it feels like it would be slower than thumb-key? How long have you been using it, and how high wpm do you have? For reference, I have used thumb-key for 6 months or so, and can achieve 40-45 wpm
