Been playing with this for 24hrs and I have mixed feelings.

The events view is a welcome change, and I can appreciate the status bar.

I do miss the pull down menu for quick shortcuts though. I used to access Settings from that, which was a handy way to access the connection options after they removed the option to choose a connection from the browser.

The quick launch (phone, browser, message, camera) bar is useless now. You can only pull it up if you have no apps open. Otherwise you have to bring up the applications view.

On the subject of the browser, when this is in card view and you want to return to full screen, if you catch the bottom edge the browser will go to the search/shortcut screen. This feels like they are moving away from the concept of a single handed navigation paradigm of the initial design.

And the I am experiencing screen tear in the browser when viewing long page (notably reddit threads). My Jolla did this when it was still vanilla but has not in other updates from Dec onwards.

One big plus is that I do find the Jolla does connect to mobile networks after comming out of black spots much quicker.
