If you have a bag you can choose what goes into the bag e.g if you have no sparkly and a bag called 'Mining' and you mine some sparkly, it would go minti the bag automagically!
+1 to this! I would be much happier with better organised bags and this would certainly help.
Maybe you would need to learn a certain level of bureaucratic arts first before you can develop the appropriate level of organisational skills to do this though.
