There are a bunch of inventory stacking and tweaking mods out there to ease up on the relentlessly difficult back and forth of being prepared or being out of money. This particular entry is a new Steam Worskhop version of one of the best mods from the game's earlier editions.
Where this one really shines is that it doesn't totally go off the rails, giving you limitless stacks of torches to carry or a free bag of holding that lets you return from a mission with all the gold you can imagine.
Instead, it scales the stack limits better so you can carry enough valuable objects back from a mission to actually be worthwhile at higher levels. It makes the grind a little less relentless, and helps you actually build up enough of a war chest to upgrade your facilities.
