Insert Zone in Project Bin is very useful but its a hidden feature. You can add the zone by shortcut ctrl+i or drag from clip monitor but the command is not present anywhere in the UI menus, making it very easy to miss (as I did for a long time). I think it should be added to the clip monitor right-click menu where we got Save zone and extract zone, as well as in the Clip menu.
"Insert Zone in Project Bin" and "Insert Zone in Timeline" you find under the menu Monitor. Yes it's even not documented. It should be available by right click in the clip monitor. Thank you for reporting. I change this to wishlist if you don't mind. And change to refactoring.
