Well, I played with the update and I would like to commend the folks at Jolla for a very nice job.
There are lots of improvements that make the user experience much better including some new swipe
gestures and better integration of android apps, cut and paste, usage of app store and such. I thought
I'd just make a few suggestions that may or may not be useful in future. They're just mostly cosmetic...

1) I like swiping up for the apps but what was wondering
if instead of the black background and the handle on top of the drawer that the swipe up transition could be
like the others where the background is a little blurred and or darkened. The black background is too
stark a contrast for me. And the little handle just adds an iota of clutter to the screen that is not needed
2) When one double taps the screen to go to lock screen two arrows appear. Not sure they are needed. Especially
after you've done this a few times.
3)I'm still not sure why the ambiences are given such a high level of priority- being readily accessible from the pull down. I would think that the pull down gesture should be reserved for something more important. Don't get me wrong. I like the ambiences and think it was a great idea, but I would think that is something you would change in system. Kind of like wallpaper, although the ambiences are clearly more sophisticated than wallpaper! Indeed, what would be really nice is if ambiences worked a little like scopes on the ubuntu phone. That is each ambience have some more functionality associated with it, perhaps with widgets or apps that are organized together on the home screen when you select an ambience (could be a way to separate work, private stuff, entertainment center (music and video playing), social network, Internet, education and such. Each category could have it's own ambience. Switching from these difference ambiences or environments from a pull down menu would be quite useful. Reminds me a little of the categorize app on n900 which basically made folders by topic. However adding customizable feature support to ambiences could be much more interesting.

Ok. I'll stop. Just some suggestions. Maybe some of this can already be done. If that is the case then sorry about that and please chime in to correct me! But once again thanks to all that have contributed to Jolla development!
