Good tip, thank you. I checked all possibilities, and it seems, that bulk operations aren't supported on most places. We definitely would improve this in next versions.

For anyone else looking, I simply edited the terminals.config file with notepad in the program folder, and replaced tags="" with tags="whatever"

Works great if you're moving everything to a new tag folder. Also, if you have multiple servers and tags to move to various locaitons, much faster to just edit the file and work through them - just copy the tag for one site, highlight and Control+V to paste the new info in at the bottom of each server's information. A lot faster than manually doing them one at a time through the GUI.

Will be better if they have a good way to group them in the GUI in a future version but for the time being, at least this is a quicker way to handle it.
