It would be really great for navigational/non-modifying actions (entering/exiting a matrix, enabling/disabling 2D slice mode, etc.) to optionally not participate in the undo/redo stack. The stack depth is limited and when navigating a lot without any modifications it’s “polluted” by those actions thus making actual modifications more and more remote in the stack until eventually erased. Just a thought.
that’s not possible, sorry.
I can make the undo step count optional if that helps
