gevansmd, you are obviously learning the "engine" in a much different way than I have seen. Much info for thought.
I am trying to meld Windowblinds with Excell because I have learned that I can use its wonderful, multi-level sorting to order (think group, as well) Blinds in to Quality, Need Fixing, are dark/light/blue/white/etc.
The hard part is picking those characteristics out of the internals of Windowblinds. Searching through hundreds of .uis files is even more cumbersome.
Keep us posted and I will try to show some progress with "clever" sorts to group Blinds in different ways.
