I'd like the ability to create more than one tag at a time without having to open the dialog with each and every tag. I'd like to be able to modify existing tags while the dialog is open, too. Simple reasons to change a tag... I have a tag for a contact and she gets married and has a name change. I create a tag and spell it wrong. Etc.
I'll look at adding a new "Close" button to the New Tag dialog, and change "Create" to leave it open. I don't much care for allowing Tags to be renamed in the "New Tag" dialog though as the user interface would be cluttered and confusing.
Apologies for the lateness of my reply. The forum software doesn't notify me when new posts are added so I need to keep manually checking!
