A feeling we all know all too well. I too carry around something to jot down ideas, fortunately my phone has a nice notepad that's convenient.
Micromanagement is a tendency I think many of us have, I learned years ago to let my employees have the space to work and be creative. They often surprise me when they find far better ways to do things than I would have come up with!
Did the idea ever come back? I've had them pop back up after a couple of days many a time.
