Sometimes, when selecting several items within a bin and using 'New Bin From Selection,' the new bin is then created at the root of the project instead of in the parent bin that all the selected items live in. Other times it works as expected. I can't figure out what causes the unexpected behavior.
Bonus bug (I think bug, anyway): If you undo a 'New Bin From Selection', you're left with an empty Bin called "Bin." For me, expected behavior would be to return to the condition prior to running 'New Bin From Selection'. Rather than having to hit undo twice to remove the bin created.
