Hey, I noticed there's like, a little art button that real cool, after the local and federation buttons how do you get art on that button area?

I think it needs to be tagged as #mastoart for it to register. Not sure if it picks up replies as well as original toots, so this reply is also an experiment!

Just found it, so I can confirm it's the tag that does the magic!
