I thought it would be nice that when you access the PC you'd have a menu appear that you'd pick 'Organize Pokemon' or 'Organize Items', and maybe a 'Logout' option at the bottom. You can use the 'Organize Pokemon' box as the PC is used now. The 'Organize Items' option would just open up a large (either 2 double chests or open a multitab menu each 1 double chest in size) where you can store items.
Also, perhaps having this option available in the config.
