So I've noticed that any meat (normal, monster, whatever) when left on the ground for some time combines into one stack which is pretty nice.
Other things should also do that like for example:
-Grass (grass gekko farms)
-Twigs (twigly tree farms)
-Spider gland, silk (spider farms)
These are the items that are mostly in huge numbers on the ground and are pain in the butt to collect (long time picking up)
