Default Deskview

Hi
Ive just had a rather strange thought.

To make the login screen nice, I can use “Website” settings … nice Logo on the
page etc.

But I am reffering to the Deskview after I log in. I remember for V11, there was a
colour background with icons for each module.

Is it possible to construct something like that on V15 ?

One thought I had was to see how “Custom Block” in Workspace can perhaps work?
Hide the left menu and create only one “Custom Block” and then define a page
using HTML ?
