I agree that it is simple to use. I just think that it can look intimidating and unintuitive (despite being quite the opposite), which is exactly what caused the failure of the original search system. Menus with dozens of clicks and submenus are really not the best way to go. Yes, text commands and XI's system are not elegant, but honestly they are workhorses that you can depend on (assuming you can type coherently).

Also, can I please just have a command for "/inv <class/job> on" to flag?
