I would replace slots with volume, and eliminate stack size.

Not the best idear, that proberbly make inventories even smaller, as for example 1 log would have alot of volume, while 1 feater hard takes any space.
Combine volume with weight, like in reality... and you proberly then run out of space with chopping a tree, while nowhere beeing over the weight limit.

Unless you suggesting to make everything the same volume, regardless their real projected ingame volume.. Like a log has the same volume as a berry.
