I think the expanding backpack was a nice idea, though there didn't seem to be an option to erase/replace a weapon or branch once added.

Part of the challenge is that you can't, which is why the connectors exist to allow you to place more parts. I understand that removing a weapon or branch would be nice, but I believe its a fun challenge that you can't, however if enough people disagree I'm willing to change it once the rating period is over.
