I noticed when I went to different tabs, like the player wasn't editable or the tab wouldn't select but I know this is early so best of success, good idea.
Hm, well that should definitely just work, not sure what's going on. Haven't seen this or heard about this before. If you'd like to share some more details, that'd be a great help! @CritNotesApp on Twitter, or contact@critical-notes.com.
A JavaScript error was reported and is now fixed - so hopefully these problems are now gone.
