However, it can be quite tedious, as first I need to open the list, click add Button, then paste the url, confirm it and go back to the page I was browsing. It can be a bit annoying especially when visiting lots of new websites every day that already have dark mode.

It would be quite convinient to have a button on the sidebar, or even just a shortcut that would automatically add a website that Im currently browsing to this list.
