So you aren’t missing any features by waiting to upgrade. In other words, everything your NLE does in Catalina, it will do in Big Sur. The two most important things to keep in mind when deciding when to upgrade to ANY operating system is that there are no “hidden” new features in any Apple or Adobe application that suddenly get turned on when you upgrade. It is better to ask: “ When should I upgrade to Big Sur?”
That’s a good question – but it’s also the wrong question.
