Idea:
I think it would be cool to have a Shell Icon Overlay that overlaid icons based on when they were last modified. For example, Files modifed in the last 7 days would have a "red" icon overlay, and files modified in the last 30 days would have an "orange" icon overlay.
This would be helpful because it would point out recent docs without having to change to "details" view in explorer. The icon files used for the overlay could use the alpha channel to look transparent, thus preserving the base icon image. Ideally the icon overlays and "ages" of files would be configurable.
I suspect this could be done by implementing your own handler from IShellIconOverlayIdentifier (see
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/programmersguide/shell_int/shell_int_extending/extensionhandlers/iconoverlayhandlers.asp)
But I'm not that advanced in my skills to do it.
Lemme know if you think this would be cool.
