I decided to change the location of the button as I spent too much time being unsuccessful in trying to line it up with the others. I also made it such that newly loaded posts are also updated with this button via the MutationObserver API (Thank you StackOverflow). This is how it looks like so far. Next I will focus on making an UI to add actual saving functionality to the buttons and make some kind of server to be able to store bookmarks “in the cloud”.
