I haven't been very active in the forum lately, but it seems like the Mac app is pretty functional. At this point, I'd like to see some optimizations to make it run a bit quicker and smoother. I have good hardware and minimal demands on the program, but am still sometimes surprised at the beachballs, etc. That's not a complaint, just a wish that the direction at this point would focus on optimizing what's already there instead of building in the last 5%.
YMMV, of course.
