Add "Add new tag after" option for tags

[WeaverSong]

I don't know if anyone else does this, but I often find myself grouping related tags, and currently the only options for adding new tags adds them at the very bottom of the list, requiring me to re-find my place and move the tag back up there. This would simply be an option to add a new tag immediately below the currently selected tag

Approved!

My idea is to have a custom popup for adding tags, with radio buttons for whether it should be before a tag, inside it, or after.
