There are multiple types of highlighting from the minimap in Visual Studio's MetalScroll add on I would love to see.
1) Double-click words to show and highlight
2) Mark modified lines
3) Show breakpoints/bookmarks
4) Show 100% of file in minimap. Zoom allll the way out.
Here is a screenshot example. http://visualstudiogallery.msdn.microsoft.com/3a50c69b-9b35-4eb2-b06a-328758afcaa2/showImage/8111
The red/blue squares on the right are breakpoints. The highlighted word "advise" shows up as red in two places in the minimap text area. Modified lines are not shown in this example.
