I'm also using Grid + GridCustomLayouts + ISBoxer Repeater Regions.

I use two primary sorts for Grid.

/Grid Config.
Layouts >> Custom Layouts >> New

Alphabetical:
[ order=NAME; ] ......without the square brackets.

Specific Toons:
[ nameList="ToonA,ToonB,ToonC,ToonD,ToonE" ] ......without the square brackets.



I use Specific Toons, when I want to just see my team.
And I use alphabetical, if I want to be able to "support" my side, via mouse click, from any of my toon's windows.
