The editor is now available for download !!
It's freeware, like free beer.
It's in english.
It runs under every kind of Windows.
It doesn't need to be installed.
It puts only 1 entry into the registry (HKEY_CURRENT_USER\Software\meybohm\proton\)
I have added syntax highlighting for Dom3 mod (.dm) and for .map files, full range of commands is supported!!
