These are some things that I do frequently that currently involve a lot of work with keyboard/mouse.
- Move current item to top of list
- Move current item to bottom of list
- Copy to… (just like Move to… but duplicates the item)
(You don’t necessarily need to give these things keyboard shortcuts by default, but I’d at least like the ability to bind to them from preferences.)
PS It would also be nice to have a shortcut for opening preferences!
