I just managed to install clockfaces on my KW88.
Using TSF launcher and Homebutton 2, I was able to install a large amount of clocks. Also I was able to repurpose the power button as a back/home button on single press and double press to power off the screen.
One thing still needs to be solved is the switching between full and small screen option (if you long press power) very often causes the clockfaces to resize to a smaller one. Manual resizing has to be performed on every widget/clockface each time.
Trying to find the trigger that auto-resizes in TSF shell.
Video and instructions to follow.
