Just a heads up, the Infinite grappling hook cooldown makes some UI elements and item images go wonky, I couldn't see the progress of holding down a button to choose a mission and most of the icons for items I was choosing were blank. It started working normally as soon as I disabled infinite grappling hook!
Why even use "Instant Grappling Hook Cooldown" when we have "Inf. Grappling Hook Charges"
However thanks for reporting, I'll remove "Instant Grappling Hook Cooldown" in the next Update.

I tried to find ways to improve the quality of dropped items but did not success finding values that could be modified for this in your pointers tree. Do you by any chance know if there is something like that ? Or you also tried yourself to find it without results ?
