New sort criteria for the sort_menus option

[CommanderC]

I have been playing a bit with the sort_menus option, and I'm missing a sort criterion that sorts according to the number of times the item has been used (equip/zap/evoke). The most used items would appear at the top, and the least used ones at the bottom. Another criterion that I thought could be very nice, is to sort items according the last time they were equipped/zapped/etc.

Are these criteria too hard to implement?

EDIT: For armour or rings, it makes more sense to use the number turns wearing the item.

That doesn't seem to be too hard to implement. Maybe add it to the interface ideas wiki.
