Hi Peter,
We would like to drag a Property of a Class from the Eclipse package explorer treeview and drop it on the wireframeSketcher work area. The product could ask me about the type (input, checkbox, etc.) before create the field and would create it with the Property's name inside. I made a picture:
This would make wireframSketcher a viable solution for customers that need "precise specification" - with rastreability from UI to Model.
PS> We have an ALM solution here in Brazil and we are studying wireframeSketcher to recommend to our customers. And we think this would be a killer feature...
