#1 is a must. I've seen other threads around suggesting the same thing and I'm completely at a loss as to why it hasn't been implemented. I have only met the occasional long or curved bone, so I'm not entirely convinced that #2 would be necessary. On the face of it, #3 is a good idea and quite a neat one. However, when you have storylines overlap and when some quests become part of a questline, it has the potential to prove as a spoiler. #4 would definitely be useful. Would make sense to have the items stored with the slayer masters, depositing in one would allow you to withdraw from another. I thought that they had a screening process for names (i.e. no swear words, racism, general offensive language) which should account for #5. Particularly keen that #1 is implemented though.
