This is not a button but a dropdown and requires 2 clicks. And this is strange because there is only one option to select. It could be replaced by a single button or dbl-click - which would be the fastest way.
I think you shouldn’t concern about accidental layer changes. Do you accidentally enter a rename mode? I didn’t even know it exists. No. I did know, but I never dbl-click lists.
The dropdown in the layer panel is there to host some more options in the future.
This is a good idea. But what happens if you try to disable the export? Would you click in the empty corner?
I will try this.
This is a bit complicated. What happens if you have scrolled and then you change the text in the edit view? What I will do is to always center the glyph that is active in the edit view. I think that should do it.
