I did some search, and all I get are:
- Universal Applets
Out of which conky seems to be the most anticipated but all of them seem to be deprecated.
I'm currently using conky and it's working great with configurations from DeviantArt. Also there's CoverGloobus as a sincere music widget(I'm not sure about it's development though).
Can someone who's been around for a while guide us newcomers?
