I just saw the memo that Helix2 was available for Droid now.... (yes, it used to be only for Nexus but it recently became compatible with the Droid...) and so a couple days ago I d/l'd and installed Helix2 to replace HelixLauncher.
So far so good! I am really liking this a lot better than Helix1. As 928Droid pointed out, I too notice that issue with the landscape view, but I'm sure that's a big that will eventually get worked out.
What I love about helix2 is that it doesn't lag or go slow when double tapping and choosing to shift over several pages. I have mine set to 7 screens and with helix1, if I ever wanted to go from screen 1 to screen 7, it would chug along and take a few seconds. Now with helix2, it zooms over with no lag!
I also dig the 3D dock added to the bottom. A very nice addition to make it just a tad nicer than helix1.
My only wish for the "dock" though would be if I could add my gmail widget to it. Not the normal email app - I use "gmail unread count" app for my e-mail. Although it's not a huge deal for me, I wish I could make that one of my primary "dock" apps that is accessible from any page. But since it has to be added as a widget and can't be moved to that "dock", I just keep it on the middle home screen. Would be awesome to be able to move it down there though.
Otherwise, the only other difference I noticed was the 3D app drawer, which is smooth and fast. I like it a lot better than the original.
