I use reset a lot as well.

I've run into the same problem where I'm trying to drag or adjust something at the extreme bottom of the viewport and the buttons pop up getting in the way - yes, you do have to stop what you're doing and readjust - I've just learned to accept it.

Granted, perhaps if MOI maintained a flag "Dragging" for example while moving or manipulating an object, then when the cursor gets within the widget area, if that flag is TRUE perhaps the display of the buttons could be temporarily suspended?...

Another option could be to hover your cursor over that area for a specified time but that doesn't guarantee that won't happen while manipulating something at the extreme bottom of the viewport PLUS that slows you down waiting for the widgets to display - definitely not a elegant solution IMO.
