Overall, v2 is very nice. And a drastic improvement over last years betas! :P As such, it is useable in its current version, and I am trying to use only v2 (however, find myself switching back to v1 to check things)
Am loving the new lease of life perspectives have in v2; the access, design and capabilities are brilliant. Also liking the inspect view being sticky.
However, the aesthetics of v2, generally, are worse. Making it quite difficult to find, view and therefore act upon actions, in comparison to v1.
In this, I mean that v1 was tight, compact and clear (different actions had different colours and line spacing was configurable); allowing me to view long lists quickly and completely. Conversely, v2 has large open expanses of white space, large rows and no colouring; meaning I get to see less of my actions, with their info spread thinly over a wall of white, and no idea if it is next action or single action (blocked are greyed text, so there is some visibility there).
Overall, the design framework is better, much better. But, I feel there needs to be the clarity that v1 had, which came mainly from style capabilities.
