Just made a small mod to remove the limit on moving items between bsbs and crates, "As many as I can carry" will default to the lower of 1000 items or the number in the bulk container that they are in. Also removes limit on moving to a container (forge, cart). You can type in a number above 1000 to move more items.
I am no longer actively maintaining this mod, bdew has kindly fixed it for the latest version (April 2017)
