One of my colleagues is teaching a class on Cocoa and iPhone development, and it happens to fit nicely into my schedule. Today he was showing different bits of Inteface Builder and XCode, and I paused to ponder the Research Assistant:
It got me thinking that a Mozilla version of this would be great as a sidebar extension, which followed me around as I navigated through Mozilla source on the web, found in blogs, pastebin, bugzilla, etc. I'd love to be able to have the ability to right-click nsIFoo anywhere (not just in MXR) and get all this sort of info I'd love to be able to do it for Contract IDs too, oh and class members, and static functions, and...We have the power.
One of my goals for the winter/spring is to finish DXR and roll that into the Mozilla Developer Resource Kit. But what about an extension like this in addition? What would you want to see it do?
