It's been a few years since I found WinApps and I'd found Looking Glass at the time then as well. Completely forgotten about it. I'm a bit rusty on the whole Windows on Linux topic :p
I've used WinApps couple years back it's great! Wish Ublue had a ujust script for it, while I don't need it anymore it can really help people transitioning to gnu/linux.
Dude that would be awesome, Ublue could them advertise it runs windows applications (as long as there is enough memory) because the seamless mode of WinApps works really well.
If you need to message me feel free to ping me or DM or use forum. I'm not very active but I do check every once in a while. Though tolerable is high praise over here :p
