Collapse indicator doesn't vanish after deleting a file

[Raduq91]

I am transitioning from cherrytree to obsidian.
In obsidian I would use just folders(no notes). Can you add a feature so that empty folders(as in no child elements) does not have an .nav-folder-collapse-indicator ?

And there is a issue when creating folder notes(I have 'create folder notes by default on'). When creating new folder there is 50/50 chance that the focus is not on folder name(so I can rename it) but on folder note.
( clicking 'New folder' at the top of file explorer, or right click on a folder and click on 'New folder')
