parent:XXXXXX tag

Should this way of parent tagging exist working like the rating:e tag does? It's make parenting multiple images easier by using the Tag Script function.

Tagging something parent:x should work. It will work with tag scripts.

That definitely works, I've used it before.

Vaguely related to this and in the spirit of increased use of pools, I'd like a pool:XXX command if it doesn't exist already.

I've already put a request for the pool:x command and text formatting in pools on the tracker.

albert, I didn't know that worked already, should have tested it, but anyways -parent:x, or rather just "-parent:" should remove the parent.

If you're tagging post #1, then tagging it parent:1 will clear the parent.

pool:x works. You can either pass it a number (in which case it'll be treated like a pool id) or you can give it a name, with spaces replaced with underscores. If a pool with that name doesn't already exist, one will be created automatically.

I'm talking about cases like pool #189 (http://danbooru.donmai.us/post?tags=hechi+code_geass&commit=Search) where I want to unparent all those images quickly because they're already in a pool.

I just found out you can unparent a post just by tagging it with parent:
