Requested feature overview description.
The Tag History pages already accept User ID as input via URL, but it isn't possible to comfortably search for it through the search interface. I would simply like to have a field that allows the history to be searched by user ID without having to manually edit the URL.
Example: https://e621.net/post_tag_history?user_id=17633
Why would it be useful?
It's already possible anyway so we might as well have it more convenient to use.
What part(s) of the site page(s) are affected?
