There is more after that as well in the linked thread. `It can auto suspend vm automatically when no apps are used. ( i have it set to 30 s ). My college uses a windows only application for tests and assignments. If i was using winapps i would have to install libre office in windows vm just to be able to quickly open document sent to me. With cassowary i can just double click file in guest and it will use linux native libre office to open the document. ( Saves storage space ) Winapps only works with VM cannot connect to Bare metal windows`

Instead of constantly rebooting my dual boot system this seems like an interesting approach for me to try. I need to play games in Windows without having to reboot from Linux.
