what you described there is more or less a os...

the feature collection is so vast and varied that one is better of having multiple, specialized apps running inside a ui that makes it simple for the user to jump between them and share data as needed.

and most of it is covered by existing apps iirc.

one bothersome detail tho, facebook no longer see microb as a valid browser. but swap the user-agent to something more "mainstream" and it works, altho a bit slow thanks to some heavy use of javascript...

heh, latest pidgin even has support for the facebook im system.

but then i prefer to use mytube (wish there was a way to redirect youtube links to it from within microb) vs canola youtube plugin, media player or youamp vs canloa music and kmplayer vs canola video.

why? because they are slimmer, more focused apps for the task they do, and i can launch any one of them directly off personal menu or personal launcher.
