Can you open a container within a container?
 

Hey, I've been trying to increase account shared bank slots somehow. My idea is to simply allow a bag to open from within a bag, can this be done?

Negative Ghost Rider!

The client does not allow more than 2 shared bank slots and no non-empty bags can be placed in top-level bags.

(Bag-in-bag only applies to RoF+ clients..but, technically, it's not supported in the emu just yet - so it's a double termination...)
