So, I'm not sure if this is deliberate, because it seems like it might be, but I'm gonna post about it anyway.
Steps:
1. Select multiple objects by shift+clicking, or drag selecting.
2. Hit the delete key.
3. Hit it again.
4. Keep hitting it.
5. Repeat steps 2-4 until all selected objects are gone.
6. Hit it one more time for good measure. (Okay, I'll stop :) )
Expected result: All selected objects are deleted at once.
Actual result: The objects in the selection delete one at a time, one with each delete key tap, in the order they were selected.
This is very interesting behavior, but it is counter-intuitive and I am hard-pressed to find a situation in which it is useful... Also, the selection box, the one with the circle at the center, remains after all the items are deleted and doesn't resize when items are deleted.
(Relatedly: Ctrl+A selects all the stuff in the sidebar and not all the objects on the current layer (ie, it isn't captured by the app script).)
