"We would recommend that all users download and use this version. It should be considered more reliable than the current Mac App Store version (1.5.4)"
As I've just lost work to a spinning ball (after discovering a bug - just filed that), I'd love to.
However, the betas (quite sensibly) run isolated from the production version: what do I do to give the beta the same brushes, tools, settings (etc etc - basically everything the production version has installed)? I understand it has to be a copy rather than a link so a bug won't wipe the production settings, but on the other hand, without the full tool environment it's only half a test to start with :).
Cheers!
