There is a good feature that I am using since forever and that it to press Ctrl+Tab or Ctrl+Shift+Tab to switch between the viewports on the fly. In the latest version it is not working. I mapped the _NextViewport and _PrevViewport commands respectively to the before mentioned key combinations but I am not happy because now they enter into the undo and redo list which is getting into my way of designing.
Can at least an option to choose between two modes be put in the settings, if it is not possible to revert it to the previous state?
