I would like to see namespaces have a meta data field. Then they could be used to point to a server’s IP like everyone keeps on asking. But there could actually be a lot of other useful bits that could be stuck in there. I’m sure there could be other directory use cases.
I would also think about rental fee times being more flexible. Maybe somebody only need a name for a month, or maybe somebody wants to have one for 10 years so they will pay in advance for it. If one year is the minimum, okay, that is fine, but it still seems like somebody should be able to buy many years up front.
When there is a “_” it would be nice if all the clients showed it as an " ".
