I'd like color-matched ming style tips as well! Everyday drip tip shape just doesn't do it for me anymore. Tank spacers would be nice too, just something to take up the gap between the buzz and tank.
EDIT - I'd also like to add a request for a native ego-style top cap. I don't use ego stuff much anymore, but it would be awesome to be able to get a native top cap for trying things like the stardust and other ego equipment. I think it might be a good idea to help pull in the transition vapers too, where they have an ego and a bunch of ego thread stuff and they want a better battery without losing all their equipment.
I know you can just get 510 extensions, but it would be nice to have external threads and not have to deal with adapters.
EDIT 2 - I'd also love to have some type of a well fitting case for my buzz too. Like a cell phone case, but for your buzz. Maybe hard plastic or silicone or something, but also having the ability to attach a leash with a quick disconnect would be AMAZING.
I can't tell you the amount of times I leave my buzz somewhere, or lose it in/around the seat when driving, etc. I'd love the ability to be able to attach it to myself for times when I might be a little absent minded and not paying 100% attention to where my buzz is. Plus it'd be really nice to have some protection for such an expensive PV.
