Hi eric, yeah it's been pretty frustrating to do all this work just to get back to the same feature set to start with. It would definitely be more fun to have been working on new features instead of the rewrite. But I do get an awful lot of questions relating to running out of memory and various quirks in the Mac version. So having those things ironed out really well will be worth it in the long run. It's one of those things where it just gets harder and harder the more you put it off!

It won't be too much longer before the first v4 beta, I still have just one big area to work on which is the viewport display.
