- Rework of DDM (Device Driver Manager), DPM (Debian Plymouth Manager) and the Welcome Screen (relies heavily on DDM and needed to change).
- The 64-bit version is now multi-arch
- Playonlinux and Wine pre-installed
- UP6 obviously
Also, DDM needs more testing. Especially for ATI and Broadcom: http://forums.linuxmint.com/viewtopic.php?f=47&t=113559
ad 3. I wish to differentiate between the unofficial LMDE KDE and the unofficial LMDE Xfce. That's why the first is going to have all the bells and whistles (I remember it was an old wish of you people to include Playonlinux and Wine) while the second is going to be lean and mean.
I'll post a RC as soon as I can, and when that's done, I'll start working on the unofficial LMDE Xfce.
