I'd really appreciate a way for the site to save the tagging and other progress while uploading, like how other sites save drafts. It'd be especially helpful when discord images need a separate media link and a message link. It would help against data loss from accidentally mass closing tabs, mobile browser closing, crashing, or refreshing itself; All that added info would be erased and there's no guarantee of finding it again, particularly when you normally insert media assets on mass first, and upload later.
Moreover, while you're opening tabs for tag wiki pages to ensure correct tag use, let's say that the uploading page itself refreshes midway, an inherent inconvenience of mobile browsers. If someone just had all 50 of their added tags to a single image deleted that will definitely increase the frequency of users just getting annoyed and uploading after applying half of the tags they'd just used, or of course can't remember the tags just applied.
These draft posts could be placed in a new section under "my uploads" called "in progress" or "incomplete". Or less straightforward adding a new image status for these drafts of uploads that can only be seen by the asset uploader.
My second request is for a way to add child posts of already uploaded images before uploading, such as when you find a much higher resolution of an already posted image to save the need of going back and forth.
