I also think it would be great to implement a path (?) feature, just for the document (contrast with a full file path) when zoomed. This should be exactly like the following plug-in idea, but just for zoom (or both would probably be better, they shouldn’t ever interfere much): Display vertical context in long scrollable document (RemNote-like auto-folding mode)
Except it should look more like this when zoomed + document path:
▾ # title / ## second heading / root2 / branch3
- leaf2
As opposed to this optional suggestion for when unzoomed:
▾ # title …
… ## second heading …
… - root2 …
…… - branch3 …
… - leaf2
- leaf3
▾ - branch4
- a4a
▾ c
