XS Community Edition/5.1
It is likely that XSCE 5.1 will precede XSCE 6.0.
Please see 18's meeting transcript for summary direction. Which we'll work on refining in our Los Angeles meetup at SoCalLinuxExpor.org Feb 21-23, 2014.
On a grander scale, see proposed features over different XSCE versions.
Suggestions are requested around our /Road_Map timing!
