MasterMFD
The MFD for those who have everything.
MasterMFD allows one to setup a simple text based file which allows users to create categories of MFDS, so MFDS can be accessed more logically and can be found quicker.
Requires the Visual Studio C++ 2013 redistributable available here.
Edit ORBITER_ROOT/Config/MasterMFD/mainTree.txt to set up cateogires.
