  • (2022-11-04, v:1.3.0) Mareq Jay: Prevent reseting activated stylesheets
    Hey, would be amazing if extension could remember which stylesheets where active, after reopening the browser.
  • (2022-11-04, v:1.3.0) Mareq Jay: add local file?
    Can we add local file? I can't figure it out. Looks like it is not possible. I don't want to start local server just for this.
  • (2022-05-03, v:1.2.0) Vũ Đinh Tiến: how about Super CSS and JS Inject
    I really like your idea :D if you want open source and I can contribute
