[Feature suggestion] Make the toolbar and the header bar vanish when unfocused (and maybe sometimes when focused).

[JamesL813]

Something I've noticed when writing longer notes is that even when the note is unfocused and the toolbar and header bar are invisible, there is still a block covering the text (left). They're also noticeable on longer notes, even when they're focused:

I think both of these could look better:

The focused window could also have the toolbar appear on hovering and the same could go for the headerbar:

This would be similar to what foliate does:

Let me know what you think!

This could also serve as a band-aid solution #40 since titled could be displayed at the top of the window
