A revival of the old Mumech curve editor by r4m0n.
It allows you to edit and see the shape of a KSP FloatCurve and copy the config to your cfg. Only useful to modders and those who edit cfg files.
Open/close with ALT+P in any scene
1.1 : add a grid and labels to the graph
1.2 : @linuxgurugamer sent me a patch with a few updates:
@4x4cheesecake's fix for the VAB
