That's a good point. At some point I ought to make a UBlock-origin style list of customisable rules.

At the moment I'm focused on translation quality, but I intend to add that.

This is a great idea. Specifically, I want this enabled when I'm wasting time but not when I'm working. So I'd like it to be enabled only on X.com. This whitelist+blocklist functionality could be a user-side setting like with Adblockers.
