It’s definitely tricky with Clear. Tap is reserved for editing an item, long press is reserved for picking up to drag and drop/sort. Two finger would need to be taught.
The current toolbar build will include a setting that enables swiping up or down to reveal/hide it, so I’m hoping that will thread this needle, making the functionality obvious enough, but allowing for that contextual use case too.
(Sorry about the late reply btw, has been a busy week here and was able to check into the forums less often!)
