same could be done regarding individual items on a bar -- hide when drive is removed, show when inserted..
That, actually, would be amazing!
I was just thinking about USB Safely Remove. It has functions that can be run when drives are inserted, started, stopped, removed. But that's a little different. Controlling on the item level would be amazing. One thing i wonder, though. How would it detect if a drive is inserted/removed several times. Would it notice each time and be constantly modifying the displayed toolbars? Sounds like a process would be running continuously for that. But the whole idea of this is cool.
