I discovered the game yesterday, and I'm totally fan, so I made a mod which is Largest chests to store more resources, and by the way, you can put stuff inside with 8 inserters (insteed of 4), so it can speed up your factory

Chests are double storage (Wooden = 32, Iron = 64 and Steel = 96) and you need 2 chests to build the large one (2 wooden chests = 1 large chest)
Here is a screen with Large Steel Chest opened :

And there is research window :


I put English and French translation
I still didn't use others chests, so I'll update my mod later

And maybe I'll check for rotation too
And why not insert new chest

Sorry if my english was bad

(I'm playing on Factorio 0.4.1, so tell me if it's working in previous versions

Update 0.1.1 :
-Fixed Order in Recipe list
-Destroying 1 large chest give 2 normal chests in your inventory
