Couple of things that would greatly improve my workflow relating to Tag Search:
Make the Tag Search window persistent until manually closed. Keeping the same search criteria around would be very useful to me and possibly others that have large tag lists. Once you press select or edit, highlighted tags would be dereferenced (unselected) in preparation for the next use.
“Select Tags” should open any closed folder structure that happens to be hiding that tag. Currently it does not and I have to know which folder(s) to open.
