Can you add "Now" buttons in meta pane to set modify and creation time.
I'm assuming you know that you know you can just run 'SetAttr MODIFIED=now' from a separate button or hotkey - and that you really do want something in the metapane itself?
Yes, I know... But another button, another hotkey... I have buttons everywhere and soon, there will not be enough keys on my keyboard without hotkey.
So I just suggest buttons to the right of dates in panes.
