It is something which bothers me already a long time. If you have multiple characters and you have to collect different armors you should have also a spearted space for those armors.
Or just make it possible to recreate every armor and weapon you owned once....
The second point is about the shaders it is damn annoying to check armors and shaders and decide on the look of your characters. That should be improved as soon as possible. There should be a easy and comfortable way to check the armors and switch between shaders.
.... that are small improvements but will increase the comfort in the game.
