These are cool, thank you! Very useful!
I have an Apple iPhone, to use them:
- press loooong time some icon in your phone (ingore the popup menu)
- all icons start moving and there comes this - (minus) sign to every icon
- top right corner has a small + (plus) button, press that
- find the VRM widget collection
- swipe right and left to choose different widgets, you can have many
Very nice.
