I'm wandering how easy / hard it would be for you guys to add a feature where you can specify a mockup as a static background. I'm doing a lot of stuff with popups and menus and find myself creating a mockup as a template, then duplicate, lock everything then overlay. After four or five of these, I hesitate to change the original.
The main thing would be at least show the original. It would be extra great if links in the original were still clickable. This helps when demonstrating navigation and so forth. (side note, if I put something with partial opacity over an existing link, the link highlights with the hint (pink) but is not clickable).
Maybe there's another way that I've missed. As I think about it, maybe a better way would be to template a group (so long as links can be preserved).
It "sounds" simple, but maybe it's not.
