I was wondering if it's ok to continue using tags described as actions and gestures: tag group:actions and gestures. I think I would find it useful to be able to see which characters, for example, give eachother hugs that look cute.

They're probably visually objective enough except for fidgeting. Usefully they're somewhat subjective so I'd wait for the others to weigh in before going further with them.

How the hell does fidgeting is look like?
Other tags are good.
Hugging girls are cute.

Fidgeting looks like a lot of the confessions. We've recently had the discussion on this on Danbooru at http://danbooru.donmai.us/forum_topics/9349.

Oh, looks cute too. But I don't really remember any "fidgeting models" around here.

I've tagged a few with fidgeting now.
