Ok. That makes sense.
You're right, it isn't labeling, though it borrows certain aspects from it.
I'll add it to the list right away.
One thing though. This seems like an incredibly complex system. Wouldn't it be better to be able to organize the whole list by the various elements (URL to match, username, etc.)? Granted, it would be difficult to acheive between Groups, but that could be worked around.
Perhaps there should be a context menu option that creates a new (probably) temporary folder that has all of the similar criteria. If you want all of the accounts that match URL to use: yahoo.com, then you just right click on an account that has that URL, and a seperate group will be appended with all of those accounts.
Heck, while you're at it, you could create a full fledged search command, with the ability to search by each of the variables, or some combination of them.
Think about it a bit. Dismiss it if you want. Perhaps I still don't understand it, and I'm trying to solve a different problem than the one we're trying to fix here.
