I have never had more than 100 items in my backpack before, im going to be honest here. I had 99, then I felt the incredibly overpowering need to smelt everything I dont use. Even things I do use!
I went from 99 to, as of now 82. Whee. I mad a bunch of scrap metal. I even Screwed with my hats! Of which I only have 4! Whee! I rebuilt a bonk helmet (because its ugly) and a birdcage (I liked it actually) and their awesome powers combined to create...a dorag for the heavy. Now I have a useless dorag, im never unequipping my soviet gentleman >:(
Also all that smelting led to 1 of each metal type. Whee. To be honest I just want to craft a new hat. (Watch me rage when it ends up being a birdcage hat)
