I completely agree with #1 and #5 - we should be able to make bolts from scratch, especially for iron men. And a daily minigame bonus sounds perfect, and would be really helpful!
The rest I'm a little indifferent about. I think it'd be cool to have a Player store, but I'm not sure it's needed.
Same thing goes for the fallen star. I like the idea, but the beauty of mining is the grind. I kind of like that this server has stayed with the classic osrs feel, and I feel like some of this may be getting away from that.
I do like the ideas, though. Great work coming up with these!
