I to used to keep all my instruments in their cases but after a long time realised that I was very lazy. If the instruments were in their cases, in order to play them I have to go through the trouble of getting them out and putting them away when I was finished.
Currently I am in the process of designing a wall mounted rack that I can use to hang all my instruments out on. They will be supported by the nut as well, and hung up high enough to be out of harms way.
