After Cinnamon, Muffin and MDM, the Linux Mint team works on yet another fork: Nemo, a file manager forked from Nautilus 3.4.x.
Nautilus 3.5.x, which will become Nautilus 3.6 stable and will be a part of GNOME 3.6, has got a new toolbar and menubar, but there were also some features that were removed, like the dual pane feature, sidebar tree view and others. And this, it seems, wasn't what the Linux Mint developers want for their users, so they've decided to fork Nautilus 3.4.x, which still has these features.
