Aye, thanks. The hamburger issue is on the todo list.

Re: keyboard navigation - yep, I think it'd be a good thing to have. How do you see it work though? Right now, once a note is being edited, you can go up and down the list with Shift-Tab and Tab, but I'm not sure how to handle going left and right... something like Alt-Left, Alt-Right? But that's probably not portable between the browsers.

I honestly have no idea. I'm not super familiar with what a browser will catch before passing to the web-page (like Alt-left and Alt-right tell FF to go to the next / previous web-page).
