We are open to suggestions so, if you have ideas or requests, please state them so we know what you want and can consider adding them (or explaining how you can already do them, if that's the case).
It's generally better to put unrelated requests into their own threads. But if it's lots of very similar things then it might make sense to combine them. As I still don't know what kind of things you have in mind, it's hard to say what's best. 
They aren't finished enough to announce in detail yet, but we will be making a lot more colors configurable as well as redesigning some UIs.
