Feature Request: Update One Library Symbol
When you click library updates available, and you just want to update one of two items and many are changed - you have to uncheck them all, one by one manually with the mouse. 

I'd like to request a way to just update one. Perhaps a new window that lists all library symbols with a button next to each for "Update."

Thank you.
