Is your feature request related to a problem? Please describe.
Not exactly, but it could be inconvenient if you edit a file and accidentally click to a different section (on mobile, could be more prevalent than PC) and all the changes you made are lost without any prompt or warning.

Describe the solution you'd like
When you have unsaved changes on either a new or existing file (no prompt when you have a new file with empty contents), have a prompt that pops up that prevents going to a different screen unless you back out, save and then go to different section or hit Save and quit, or discard changes (the names of the buttons can vary but should convey similar meaning).

Describe alternatives you've considered
Being more careful when clicking is one but mistakes happen so it is good to have a fail-safe/safety net.
