You'd think Mom Bethy would take a point from Oblivion modders and introduce denok option for archers, but no... again I have to ask modders to do it.
Please?

oh, and better coin sound. When I touch them sometimes they sound like paper money. And Skyrim is not that backward as to use paper - everyone knows you use paper in toilets, not shops

Press ready weapon to denock arrows

Have you tried pressing R (putaway button) when you have your bow drawn with your arrow out? Works for me to put the arrow away.

Whenever I use a bow, I draw the arrow and then press the sheathe/unsheathe weapon button and it automagically denocks the arrow without putting the bow away. Am I missing something here?

Denock is already available. Just hit the 'ready' key after drawing a bow to put the arrow back. Same with magic.

I think that's a bug. When i take gold it makes the default pickup sounds, but if i pick up gold right after that it makes a "coin" sound.
