Dno, never say never. Before I started S3D I considered coding a game launcher with all sorts of features I had in mind. I have never (to date) tried SH3Commander so honestly wouldn't know what it all does (only know the rough details). Then, I figured, due to the lack of good mod tools, and as I noticed SH4Commander might be picked up by someone else, I dropped my own idea and started on S3D.
If nobody picks this up, and S3D development settles down (meaning 1.0) I may take a stab at it. I guess I'll be too busy with S3D forever though...
