Undo view change

The problem that this feature will solve:

I frequently find myself accidentally changing my viewpoint, most often by orbiting when in sketch mode instead of panning. I’d love a key combo to undo this view change and put me back where I was. Failing that, I’d love a keyboard shortcut for the “normal to sketch” button that pops up when I’m in this state.

Brief description of the outcomes that you expect from this feature:

I’d like this undo list to be separate from the modelling undo list that already exists – it’s frequently useful to be able to undo model changes without moving the viewport, and vice versa.

What can’t you achieve without this feature?

This would solve a UX pain point for me.
