Would be great to see a launchbox on Linux. I've been playing around a lot with Launchbox on Linux over the last few days and I can get it to run via Wine Proton, but it's extremely slow and constantly freezes.
Something with this (Lutris wine-ge-Proton Logging):
Started initial process 3377 from gamemoderun /wine-ge-8-26-x86_64/bin/wine /LaunchBox.exe
