The examine option on right-click is pretty much useless.  It could be much more useful if we integrate it with guides and bestiary.

• Examine on any NPC that has a bestiary entry opens such entry
• Examine on any item relating to a skill opens that skill page [example:  examining yew tree opens woodcut skill page, examining logs opens fletching skill page].
• Examine on ring of riches/charged dragonstone amulet/etc lists remaining charges.

I'm sure others could expand on some other good uses for examine as well.
