Just installed LMDE MATE and totally happy with it.
As for now, most of my installed software is mate-*: mate-text-editor, mate-terminal, mate-file-manager (Caja), etc. And there's no disc burner. Quick googling provided me with a link to GitHub repo with Rejilla, a fork of Brasero.
Just curious, why LMDE provides MATE desktop environment but doesn't provide a full set of MATE applications?
I'm using Xfburn for now, but it depends on packages from XFCE and this fact bothers me.
