Kerbal Space Program

i love the addition of inventory items but i feel there needs to be some tweaks. lets say you have a kerbal with both a shoot and RCS pack but you want to add an EVA experiment kit, in storage on your shuttle you have a stack of 4 eva kits(kerbals can only hold 1) but you have no room for the para-shoot so you are unable to trade out for the eva kit that's OK ill just toss my para-shoot on the ground.(this should be added to the system)
