But, there isn't much to peek in sailfish. Hidden clock and statusbar indicators is just a lame excuse for existance of peeking feature. If you could peek into last used apps screen, that would be really useful productivity feature. Or if there's a fullfeatured widget layer to peek into, but covers?..

There are two features birthed by marketing department in sailfish - ambiences and peeking - both are too halfbaked to do anything useful in the os.

Just give a real value to them, Jolla, give'em a real function, let me peek last used app contents, let ambiences be smart and automated (aka profilematic) and also implement 'a pack of cards' type of switcher for quick app switching. Also make swipes configurable in settings, introduce swipe zones, swipe from tophalf or bottomhalf edge of a screen could easily perform different actions, just let this be configurable by an user, to not to confuse first time users too much.

But i doubt anything like this will ever be implemented.

Edit: I think SF v1 was much better conceptually, it felt almost complete on its last iterations with the help of patches. SF v2 is more like moving target, for example, Jolla introduced an 'empty' swipe at the first screen of the app drawer - when you have multiple pages of apps, and you are at the last page, swiping quickly back to first page, you should notice this. It is frustating for a thumb, and not a good design.
