It's really sad, and in my opinion poor customer relations that VSL have provided no information on their plans and timeline for M1 compatibility for about a year now.
I've always felt that VSL is a PC centric company from comments by the developers/programmers. It's likely they develop on PC first and then port over to MacOS which often results in disregard of Mac development guidelines and aesthetic issues as well as slow adoption when Apple makes changes to the OS.
They are not willing to officially say so, but I do believe VSL would actually prefer if everyone just used PCs.
