I’m sure Pixologic is aware that their tool management is clunky and inefficient. The way different tools quickly crowd up the limited space, no folders/groups for subtools, things like that. That’ll have to get redesigned, sooner rather than later.
Getting rid of, or at least hiding the legacy pixol stuff would also be great. Having to press ‘t’ to edit, faffing about with accidentally dropping to canvas, the three different ways of saving different aspects of your work, etc, these should all get streamlined.
I also think the default brush palette is needlessly huge. A fair number of those brushes is very specialized, and the workhorse brushes (move, clay, standard, etc) get lost in the noise. There likely should be a hierarchy of some sort. I mean, the current system of alphabetical selection works ok, but isn’t quite elegant enough.
Last but not least, 64-bit, goes without saying. 
Anyway, can’t wait for the recap videos! I live on the other side of the world, watching live unfortunately isn’t an option.
