~Make different layout for mobile and desktop and let user choose which one he wants to use, similar liek youtube video size options, notes beside or under the video.~
Layout is fine, but it totally doesn't work on mobile (firefox), enter key does not create note, either it's different key code or something else. Quickfix would be to create button when on mobile, something like add note before the save button, it should fit nicely.
