Sounds like we need a WSL in the other direction - have a Windows subsystem for Linux, so that your $distro integrates with Windows and you can run apps on Windows while having the window show up on your Linux system :)
Aside, surprised and disappointed in that you can use Affinity tools, which is very cool, but kind of sucks that you have to jump through that many hoops. Would be somewhat nice if Affinity themselves gave you an install script that could self-detect the major Linux variants (Fedora, Ubuntu/Debian) and install more directly.
