I just hope they do make the upgrades you can make to your char troggle like. so you can turn off the infinite ammo, or the no falling damage. And please, pray that they won't make the dual wield pistols or SMG's permanent again! ! My character looked more awesome with one pistol then with 2. =P
The upcoming save editor will allow you to toggle all upgrades, along with stuff like reinstating all the gangs postgame. Corrodias took over development from Minimaul and it's almost ready for release. I had a chance to test out the latest build last night and other than a few minor interface things was totally solid.
Also, the very first thing I did was turn off dual wielding.

You are doing awesome work! <3
