Okay, Tanglu 4 "Gnome" is unfinished. I understand it.
I believe the developer says it himself.
The topic is also done for me.
I have now switched to Siducation.
Tanglu 4 has for me too many construction sites.
(Shutdown takes long, K3B is missing, there are difficulties when replacing Nautilus by Nemo - the desktop is empty despite dconf customization and shell commands. The problem already existed at Tanglu 3. Synaptic is missing the toolbar and so on ...)
