Currently, if alt-mode is enabled, the warehouses show a blown-up icon of some items inside. Especially for the storage logistics one, this isn't terribly useful and imo looks ugly. Having a toggle to ignore alt-mode would help out with this.
Warehousing 0.2.0 added a setting for whether the alt-mode icon should be scaled. It defaults to on, but can be turned off if you would prefer the icons not be stretched.
