Mouse-hover over flags
In a person's posting "signature" with username and flags, it'd be nice to be able to mouse-hover over the flags and get a tooltip with which language that's supposed to represent...I assume they're not all fully obvious to every single user (who uses the Web version on a machine with a mouse).
This would become really useful when we get to languages that aren't national languages (I know we already have Esperanto). No matter how well you know your flags, it's unlikely you know the flags of each Indian tribe and Indian state and the 800 languages of Papua New Guinea and dead languages and con-langs and…
That'd be great. I know most of the flags by now, but there's a couple that I always get wrong.
In fact, I've considered making a userscript to do the same thing. In theory, it would be possible (the class name of the element tells the country code), but my attempts to write scripts like that have proven futile in the past.
Right, of course. But it would be fairly easy in the code to create a mapping of country codes to language names and look up the corresponding "proper" name to display on hover. (It's harder to display the language name using the language the user is viewing the site in, but that's possible too. I've seen it done in another script.)
