I've used the carribeaner to convert a first aid kit to be connected to my backpack.
I understand that i need to equip/remove the item from the backpack in order to be able to access it.
I usually 'equip secondary' to quickly get meds out while moving around.
there is a minor issue, where, after it is equipped, i am unable to put items into the container until i scroll down and look at it's contents manually.
(as in, can't put anything into the container until i change the inventory window to that of the container) Once that's done, it works just fine. And i really appreciate how 'unequip' actually lets it go back to the backpack.

It's not a big deal if this can't be fixed, but wanted to bring it to attention
