How do we tag our scripts ... ?
I think it's very simple: enter Edit Mode; then
ScriptGroup
type your group name

Re: @©TriMoon™:

No idea where you took that screenshot but im unable to see that anywhere...

The new UI is in effect since that was posted.

Currently click "Edit Script Info" and it's now up in the right side of the page... don't forget to click the "Save" button to the far lower left under your Description after you add it to your group.

OK, but how can I add a non-existing group? it returns "No matches found."
