Small random tweaks and hooks, for example adding button to auto invoke youtube-dl on YT and twitch(using custom URI), Hackaday comment system enhancement(highlights new and your own comments in diff color), style injection instead of Stylebot on few pages (using 50MB permanently for plugin just because I have two custom styles on pages I read maybe once a week really hurt my brain, even with 16GB onboard:/), gmail url tracking stripper etc, small stuff. I pretty much imported all of my userscripts from Opera Presto, wouldnt make the switch if there was no way to inject own .js code quickly and painlessly in Chrome/Vivaldi.
