Here is a good idea from Joe, KF7MIX:

1. in the message inbox view, allow multi-select using either shift or ctrl, to allow the selection/deletion of more than one message at a time.
2. alternatively, allow the use of the Delete key, instead of just the right-click option

I have no idea how to implement these changes, but surely one of you can whip this out in a minute ;) !
