Welcome to ZDF!

Already in, a basic Vanilla Doom feature -> https://doomwiki.org/wiki/Linedef
Linedef flag 0x80 (Always hide in automap)

So, I noticed that when examining a map in a very detailed map, the absolutely monstrous number of lines in the map make orientation very difficult (decoration sectors inside a room, for instance).

So I was wondering if we could MARK some lines in the map editor to be “invisible” just in the map, to make a more schematic map in game to help with the navigation.

Thanks.
