This is my first try, but this is my attempt to add "Bookmarked Fics" as a drop down option in the header of AO3.

The code was mostly copied from JaneBuzJane's https://greasyfork.org/en/scripts/426732-put-marked-for-later-button-on-ao3-home/code. I don't know if it works yet because I have the coding experience of SCRATCH and don't know how to test the script without uploading it. Bear with me!
