I made a redesign of the XFCE logo recently, because I had different idea about mice.
The source svg available here: http://zamiere.deviantart.com/art/Exii-347216604
I prefered with whiskers :-p
Xfce is NOT Xubuntu. Bugs in Xubuntu don't mean that Xfce is buggy ...
I honestly feel like the current logo is already simplistic/ minimalistic enough as is, but that is nonetheless a good design!
