(I don't know if I can say this in a way that makes sense, so sorry if it doesn't)
One little thing that kinda bothers me about Idol Complex is that when you change the type of a pre-existing tag (like a tag which should be a character tag but is a general tag instead), other posts with that tag don't automatically update the tag order (Y'know, Idol > Character > Copyright > Photo_set > Medium > Meta), only if you edit the tags in them. I kinda wish that was fixed.
Again, sorry if my comment doesn't make sense, and sorry if it's too long. I edited the tags in this post. :P
