I would like to have the ability to decide how much to nudge by in S1, particularly in MIDI editing, but would be handy for all types of nudging. I do a lot of very precise MIDI phase alignment to real drums and even with the grid off, so the nudging is smaller (Not sure what it defaults too here) it's still often too much movement. The ability to nudge in samples or milliseconds or any value of my choosing would be fantastic and save me a ton of workflow time.
Even the ability to call that out in a macro would be fantastic as the macro for nudge doesn't have any arguments.
