That said, I find user scripts superior for most tasks, despite some lacking UI niceties. They are easier to share, use, and crucially, audit—be it in terms of scope, permissions, or code updates. Plus if Manifest V3 is any indicator, the future for browser extensions looks bleak. While I don't agree with this direction, it's probably for the best for the majority of users, like my mom.
Your effort is commendable; however, should you find yourself looking for a viable pivot in the future, I believe the user script space is primed for innovation and could offer a good alternative.
