Offtopic:
nobody would pay for BTT on linux
BTT offers sooo many (I cannot stress this enough) good stuff, so definitely a lot of users will pay, including me. But BTT for Linux won't happen :\ .
BTT is the only reason I would continue using macOS. Before I discovered BTT, I regretted my choice to use macOS/MacBook for a workstation.
On the topic - I'm relieved that BTT works on macOS 16, hopefully it will stay that way before the final release
