I've just tried HEM2 for a month and I'm really disappointed. HEM1 was way better in my opinion. The new one is full of annoying bugs, and isn't customizable enough (for example, you're not able to disable the graph and results in the active session tab).
All in all, I don't like this new interface at all. I think I might actually be switching to PT4 when it's done... This HEM2 feels like beta, I don't know how they can sell a product that is still this buggy a couple of months after a release. It's like buying a really buggy video game - fail.
