This is an excellent tool.
Took me a little while to figure out how to edit my preset library and in case anyone else is struggling you need to choose, BFD3 database (under Mode) and Presets (under Type) and all the presets names are in, C:\Me\AppData\Roaming\fxpansion\BFD3\Programs.database (it actually finds it for you when you)
I had been trying to point it to the system presets folder in, C:\ProgramData\FXpansion\BFD3\System\Presets
and wondering why nothing was listed.
