The Tavern

It does not make much sense to see number of scrolls/potions used in morgue unless they are zero IMHO. Character used 10 scrolls between level 15 and 18. How many of them were teleportations? Acquirement? Enchant weapon?
I mean it could be much more useful to see specific scrolls/potions used, also it could allow to teach new players easier: were scrolls of enchant armour/weapon used too late, how many teleportation scrolls have been used, how many potions of heal wounds have been used, how many scrolls of blinking have been used etc.

This is pretty doable but there's some fiddliness involved compared to the existing implementation for other items, I put off working on it a while ago but might get back to it sometime. Patches welcome in the meantime!

If the problem is related to using unknown scrolls, then probably it can be fixed by having a separate "unknown" item. This can be used to see how people id potions/scrolls
