- MacOS has handy text navigation shortcuts: alt-arrow to go back a word, alt+shift+arrow to select a word, etc. These don't work, and I'm too used to them to stop using.
- I'm using Colemak keyboard layout (L key inserts letter "i"), but keyboard shortcuts don't respect it. So in my mind I have to press Cmd + U ("u" is mapped to I key) to make text Italic. Again, this broke my usual habbits.
- Common MacOS shortcuts (even Cmd + Q to quit) don't work.
I like the ideas behind this editor, but now I hope someone ports it to HTML + JavaScript, so it works keeping all the OS-provided affordances.
