I wish there was a way to reorder tags with Xkit or something. I changed the tag I use for my art for tracked tag purposes, but not all my previously tagged posts had it in the first 5 tags, so it’s mostly my newest stuff in the tag.
A script (OR HEY HOW ABOUT CLICK AND DRAG TAGS TO REORDER THEM, TUMBLR) to reorder tags and retroactively make a specific tag be first would be cool.
