I was thinking more in general but I can imagine there's some we'd want to appear in Chris's Gallery or Bobster's Sportsbook as well as forum_list but NOT on the portal homepage.
I have made a simple example how to use position and size to create widget pages:
1. position (inside column): 0 goes to top, 2. position: (number of column): 0 is first column, 1 is second column, etc. 1. size: number of rows spanned, 2. size: number of columns spanned.
See example in picture where position and sizes can be seen for each widget.
Excellent stuff thanks Henrik ... what Mr Rocks should use on his overview page to explain how it works as it's not immediately obvious to nubs such as myself.
