I’ve noticed at least a couple of people mention this in other threads, including:
I second this. I’ve used AS for years and am pretty proficient at it, and am now getting into JXA. I just discovered Script Debugger recently and am very impressed, except disappointed that I can’t now use it with my new JS goals.
So yes, I too would be more than willing to pay more for a SD that also supports JXA.
Could this happen anytime soon?
