Firstly, the idea of different colour pens – introducing blue. Using different colours to represent info/thought callouts as opposed to arrows that indicate a change.

Also the Notation needs to accommodate changes in approach and UI … something better than just scribbling stuff out or starting again … a way of allowing an idea to progress whilst making it clear where the thought started and what the final decision was without cluttering the interface.

The idea of abstracting global and page elements … so get your global design done and out of the way but also making it clear that all pages inherit from it … some sort of basic tree diagram. This also then filters down to screen regions – your deltas.

Also, want to explore the idea of showing how a delta sequentially changes and why; either in response to user input or just time; like with my boxed comic-style 2-panel storyboard of the password field in the top right of the photo linked to above.

Pulling out deltas is fine, but what about inserting them? How do you show "This would be inserted here when this meets this condition" without confusing existing symbols such as your callout and workflow arrows?

I want to explore the tree and the panel storyboarding of deltas a bit more over the next few days – just need to find some real work I can apply this too …

Thanks for referencing my blog. I have a few ideas – trying to tackle the idea of over-time interaction/response … I like the delta box but it can make it hard to keep track of the original screen; hard to hold that in your head.

Might be better if somehow we can flip that around and centre around that original screen state using callouts coupled with screen region frame-by-frame storyboarding. I'll do up an example tomorrow.
