Hello,
I enjoy using WireframeSketcher a lot at the moment and think of ways of improving it. I'm going to submit some of them here for approval. I stress that I am not grunting about the current state of WireframeSketcher, I just want to submit possible ideas, which may be discarded at will.
Feature: Contour Line Configuration
Description:
Giving the possibility to configure the line style and weight for some of the UI elements. Weight might not be really important for a wireframe, but the ability to use dashed or dotted line styles for the elements borders could be useful, to make a distinction between real UI elements or just information boxes for the reader, or to show some emphasis.
