I am going to attempt to create a standalone editor for the engine before I cover an MV release, as I believe the only issue with MV is that the editor itself is not compatible.. :/
However my progress on the editor has been a bit slower than I'd like ^^; I do have a framework built for it, but it may take me some time still to get it all where I want it..
Hopefully at the end of that though I'll have a working version for MV.
