I'm not the first to consider this proposition (
http://forums.rockbox.org/index.php?topic=2413.0), but it certainly has been a while (unless I missed the discussions elsewhere...).
There seems to be an ever growing mass of plugins, yet no categorization method implemented. The list could be divided into a community decided set of categories such as "Games," "Tools," "System," "Visualizations," etc.
I think it may even make sense to move a "Games" category to the same menu level as "Plugins." This may be extreme - especially for those who don't have a color/large LCD DAP.
What are your thoughts? Are there any issues or systems in place that will inhibit this feature? The previously mentioned thread mentions the Voice feature being incompatible... is that still true?
