What it dooo : 

Vanilla bags are shown on the back, the bags that are affected are 
- Linen Sack

- Mining Bag

- Sturdy Mining Bag

Why it was made  :

Steve Harvey : Give meeeeeee immersion !

These should be on the back , especially the sturdy mining bag i don't see it being carried by hand all the time

Personal Notes: 

For now only bags are handled this way , a lot of mods already do this for their items anyway
but if someone had an example i don't mind adding a compat file for a specifc file

Support me on , I take requests =) :
