One thing I've noticed however is that the toolbar doesn't show up at all, at least on Android.
Another issue is that the editor sometimes opens blank, even on an existing note. This is unfortunately quite random and I wasn't able to replicate it with any specific note in particular. I assume it's some race condition, perhaps the editor not being fully ready when a command is executed.
Edit: Ok I've just realised that the command are only keyboard activated. Do you plan to add the toolbar next?
