Hi Alain.....
i modified the file dirincolor.zip from the skin by Pongo so that the icons from [Only registered and activated users can see links. ] can be selected from the menu.

I used dirincolor.zip from the last skin from Pongo (22.08.2019)
Changes have been made entirely and only in dirincolor.zip and there is no need to change anything in the skin that is, the additive is completely self-contained.
But.....
There is a problem with the rendering of most icons.
If you are interested to send you and look at the icons.
The important thing is to keep the names of the icons (phasename) because with these names are described in all files.
Regards.....
