RFC: making the resize feature on the activity screen better visible

[Fania Bremmer]

** Proposed Change **
Making the resize feature for the boxes on the activity screen better 
visible, maybe inceasing the size of our little "scratch icons" on the 
right corner? Or any other suggestions to make it better visible?

** Reason For Change **
One of our coolest features, that is no user detects by himself, but 
after seen it once, uses it all the time....even more important now with 
the new vertical resize....
