Notes

For the inventory editor open your inventory then editor will be filled in chaotic order with the inventory contents and for safety reasons inventory editor parts are unfreezable.

Just in caase try to save your game frequently while using the trainer.

Max Item Quality:
Switch it on then open your inventory and disable it after otherwise it might interfere with crafting system.

Easy Craft :
Very important: This option enables you to craft anything with abslolutely zero requirements but with a small flaw, it replaces the Pockets with the craft requirements and some random items so make sure to preserve your pockets before trying this also enable this WHILE YOU ARE IN THE CRAFTING SCREEN then disable it before closing the craft screen.

I'm not sure but the changes caused by this option might be permanent.

Warning: Don't try to use this option too often as it may cause crashes.
