All the facebook, twitter, and various sharing icons clutter up web pages almost as much as the advertisements. There should be an included on/off button option to block these (same as the settings for lists for the different countries) or at least the ability to import the filter lists the way ublock origin does it.
I’m sure there are other filter lists, but either the Fanboy Anti-Annoyances list or the Fanboy Anti-Social list both work great with ublock origin and should work fine with Brave’s integrated adblocker.
I know you can enter custom blocking filters in Brave, but I couldn’t get it to work and simply importing one of the existing filter lists would be much easier.
Hope that makes sense. Good luck with development.
