Thank you! You are talking about my Window Preview Class that was also shown in #604. I use it so much I wonder how I lived without it.
The name is kind of confusing. It originally was just for Window Preview but then I realized it would be useful at runtime on a “live” window. I’m thinking of renaming it “Window 411 Class” as in 411 = Slag for Information. In presentations I can use other hip slag like “let’s use Window 411 to give you the Low Down on this List Control”
