When I try to lad the game with your mod for the first time I got an error

Thank you for the report. It should be fixed in the next version (available now).

Yap, works now. But maybe you should make storage size bigger. In comparison to Angels warehouses yours take 4 time space, but can store a lot less .
P.S. The mod idea is great.

Thanks.
Increasing the storage size would mean significantly reducing the icon size, which wouldn't look as nice. They're not supposed to be mass-storage replacements, only visual helpers. Also due to their size you can fit a lot more inserters/loaders on them which is useful for sorting systems :).
