adds "add user to your favourite list" button next to users while scrolling through feed to save a few clicks (be sure to edit the variable "lists")
当前为
Add a user to a list in 1 click instead of 4 clicks and scrolling if you have many lists like me.
1) adds a button for each list next to usernames visible on the page (you specify which lists you want)
2) when clicked, it'll open the user profile in a new tab
3) clicks "add/remove [user] to list"
4) selects the list name
5) save
6) close tab
