As someone who suffers from Repetitive Strain Injuries, the change to stacking for wood, plant fiber, stone, etc. is greatly appreciated. While I can understand not wanting to allow players to cram a fighter thrall full of 1000 steel bars or the like, I think there are still some items that could merit stack consolidation.
My suggestion would be to increase the stack size to 1000 for all non-perishable resources. This would include ironstone, coal, starmetal ore, brimstone, hide, fur, cochineals (those annoying red bugs from cacti and the volcano trees), crystal, seeds, resin, ichor, etc., but not processed goods like steel bars, aloe potions, or shaped wood.
Failing that, please consider adding a Drop All button when someone does an inventory search on a particular item. I’m not kidding when I say that trying to drop 100s of stacks of cochineal bugs really makes my hands sore.
