Several people expressed a wish to hide inventories of parts with many Kerbals.

I wonder if it's possible to a ModuleKISHiddenInventory, which would hide all the inventory buttons from a crewed part's tooltip, but leave the items in Kerbals' pockets untouched.

I can show only one button "open inventory" (so I hide other one if detected), and add on the GUI inventory screen a "previous" and "next" button to iterate through each inventories.
What do you think ?

That's probably a good idea. I would like to see this feature for pods with 5+ Kerbal seats.
