Mark For Later, Subscribe, Download and Bookmark buttons on all work and bookmark lists
Adds buttons for Mark for Later, Subscribe, Download, and Bookmark anywhere on AO3 where works or bookmarks are listed.

"Bookmark" will open the bookmark form, so you can add tags, notes, etc as usual. Creating bookmarks, "Mark for Later" and "Subscribe" all happen in the background, and the page doesn't reload so you won't lose your place in the list.
You can click each button only once, then they're disabled. The icon on the button reports the status:
"Download" will, like on a work, provide a submenu to choose the download file format.
You won't always see all four buttons:
The script doesn't know if you've previously marked something for later or subscribed to it. You won't get an error for clicking them again. Note that AO3 can double-subscribe you to the same work, which might result in multiple notification emails.
The submenu for "Download" is finicky, because AO3 didn't design it with the intention of showing it in work lists. I've added CSS tweaks for the Default and Reversi skins, but it might still be cut off. If you have a custom skin, you might need to adjust that to make the submenu display where it should.
If you have a script for automatically populating some info into the bookmark notes, it probably won't do anything in the work lists where this script added the "Bookmark" button. Nothing I can do about it, unfortunately.
There have been several scripts (e.g. 1, 2, 3, 4, 5) to provide these buttons before, but those for MFL and Subscribe have broken after a recent (Sep 2025) change by AO3, which is why I created my own version. Those scripts also jump to the top of the page after a button is clicked, which I was able to circumvent.
