This could perhaps be taken to the next level by extracting all the icons, converting them to a web-viewable format, and creating a web-viewable list with at least the file they came from. It would be better if the site could do some kind of search-by-image, and if some better indication of purpose than the file name could be automatically generated.
Net result - a wee bit of the documentation that would have been provided for users if the Android developers actually meant the status bar to be useful to those users. There'd still be the problem that the icons are too small for some of us to see, and the usual un-pinch gesture does NOT work to enlarge them. But it would be a small step in a useful direction.
