Is there any way to delete unposted images in the "My uploads" tab? I've got a lot sitting there that I'm not going to post and don't want to accidentally post (mostly duplicates). I saw there was some talk about this a few years ago and that there wasn't an option to do so. Has there been any change, is there any way to remove them now?
The closest thing I’ve seen is this userscript you can find in about:userscripts. It lets you hide the assets you don’t want to see and has a toggle button in the assets page to show/hide your hidden uploads (they’re not deleted, you just won’t see them). Try it if you can install it.
If there's one small mercy to any stupid quirk of Danbooru, it's that there's usually some kind of userscript to get around it at least. We have enough people able to do that.
