I’m on mobile so don’t have the link handy but there’s a fork called Thaw that has been getting frequent updates

Oh! Thanks for that, I hadn't realized Ice's maintainer had stopped working on it: https://github.com/stonerl/Thaw

I had been using Hidden Bar but gonna give Thaw a shot now. Looks a bit more full featured and under active development!

I’ve been using this for years. It’s simple and works perfectly: https://github.com/dwarvesf/hidden

KDE has it included!

Ewww, it's free and opensource!
