I'm not sure if someone else here has mentioned this issue yet, but I've been having the problem of manually picking up every individual arrow/rock/quarrel or stack of them on the ground every time I have to deal with a tough monster by ranged attacks, for as long as I remember during my history with ADOM. I suggest there be an option, set to "true" by default, to automatically pickup all missiles that have recently been thrown. There can also be a separate option to include weapons not normally considered as missiles but can be thrown, such as daggers and hand axes. I feel this is a quality of life feature that every ADOM player (and PCs who heavily rely on ranged attacks) can benefit from :)
