Mini-CAD: "Preferences" icon
Using the "Preferences" icon , you open the following dialog box:

To provide better clarity, you can provide the Mini-CAD layers you are working with, with a designation. This designation is shown in the program status bar as a drawing layer:
= Drawing layer: Site Plan/Selection layer: all layers
This makes it easy to see what's on your displayed layer and, if necessary, to toggle the layer to add more Mini-CAD elements. The designations can be saved in an ".ebene_ggu" file and can be reloaded for use in other files.
In the lower group box you can modify the appearance of the pop-up menus via the column number. This setting only applies for a previously started Mini-CAD system.
