Earlier they removed the transparency in the GNOME-Terminal & now this. Why are they ruining GNOME? I'm thinking of moving to XFCE4. But Dropbox doesn't works there. Mate works fine but no graphical effects .
There is no reason dropbox should not work in XFCE. You can install dropbox in LinuxMint XFCE variant and Manjaro XFCE version. I personally use Openbox. It does not have all the bells and whistles of heaviweight DEs but its low on resources and is blazing fast.
Here goes my 10' netbook screenshot running Archlinux + openbox. It boots up in 10sec and shuts down in 5sec....pretty impressive for an atom based system. Do notice the dropbox applet on the system tray. Anyone wanting a similar lightweight yet fully functional system has two options: crunchbang and archbang. Everything works in these two distros. Dropbox, libreoffice, pidgin, firefox...you name it....everything runs fine.
