At our research chair (https://mnm-team.org) we used QuIDE (http://quide.eu) quite a lot to try out quantum circuits and teach quantum computing to our students. As many of us are not using Windows that was kind of annoying, because it was only running on Windows.

So one of our students refactored QuIDE for Windows together with us with Avalonia UI (https://avaloniaui.net/) for cross platform use on Linux, macOS and Windows.

I think it's now in a state to be used as replacement for the old version. We're happy about new users and contributors.
