Maybe the 2d cursor tool button should be removed from the toolbar when not in use?

This won't work well in a few cases.

Why not have an overlay option? Then the cursor can be on/off or depend on pivot?

I guess this would work, I later realized there will be issues like this too. I mostly wanted to point out, that 2D cursor would be used quite rarely and it should not be visible by default.
Then question is, whether it is better to have simple on/off option or option to auto hide. I would probably prefer simple on/off switch, because not all operations that use 2D cursor are modal. So I will make patch for that.

This may be still useful feature perhaps, so I can update it for more use-cases but it will have to be maintained when new features are added. Sounds like it would be best if there was flag in SpaceSeq that would indicate if 2D cursor is "in use".

I'll post here too, then: Imo, some more "intelligence" should be build into this. Right now the 2d cursor tool is visible when the tool is not. This will lead to confusion. Either both should be switched on/off with the overlay checkbox, or the 2d cursor should be automatically switched on when the tool is active, and automatically switched off when the tool isn't selected + pivot is not 2d cursor (+ snap to 2d cursor(if that is ever going to be implemented)) - but can be manually switched one in the Overlay settings.

NB. letting one setting determine another setting is not a completely otherworldly ex. Zoom to Fit is automatically disabled when resolution is manually changed.
