🏳️‍🌈 Happy Pride Month!

A month has flown by since our last update, and we're excited to reveal the new features and improvements we've been developing. Hopefully, we've successfully delivered these without introducing any additional bugs. 🤞

What's new

  • 🦊 Support for Firefox is finally here!
  • 📝 Check out our brand-new Changelog page. We think you're going to love it!
  • 💅 The menu bar icon has undergone a redesign to give it a fresh new look.


  • We've tweaked the behaviour of the full size indicator, it won't show up each time you focus on a new input field within the same app anymore.
