It seems to me that it is impossibly difficult to manage the multitude of domains I have, either with Rackspace (Click and Name) or with other providers. I took the time to build a mock of what I think would be a great addition to the Rackspace Cloud control panel.

What you will see at http://www.flickr.com/photos/quantumdynamix/4927646962/ are my initial thoughts for the Domain List. This list could be contained within the Hosting tabs due to its direct relation to hosting. On the list screen, various bits of information could be seen at a glance, including the domains expiration date, initial registration date, and site association. A few things within the mock really stand out to me and I would like to discuss further.

Status icons

These icons give the user a quick reference regarding the general status of the domain. Green would mean the domain is working as expected. Yellow would mean that the domain has a warning associated with it, such as a pending expiration. Red would mean that the domain is not working, either it has expired or its DNS has some kind of issue.

Site List

Clicking the site name within the site list would take the user to the area of the control panel where that site can be managed.

Domain

The user would click this link to manage the domain. DNS could alternately be managed from here. Renews could be performed from here. I would love to see automatic reoccurring payments occur from within here too!

Registrar

I thought this was a great feature idea. When the user assigned the domain to a site (which is where all of this domain information would be created from), the user would give it a registrar (if they wanted to). They could select this from a dropdown of common registrars (which would have their management URL pre-assigned to them) or select other and type in the registrar name and management URL. Domains registered through the Rackspace Cloud control panel would simply state that and be managed via the control panel.

So, hopefully this is the most through feature request ever! I hope you enjoy it and I would love to hear your feedback.

I would like to have Punycode support for the DNS offered with Cloud Servers.
Punycode is an encoding method that encodes Unicode characters to some ASCII code that is allowed in the Domain Name System, as defined in RFC3492 http://tools.ietf.org/html/rfc3492
As it converts into standard ASCII code, it won't harm the existing system for supporting it. Simply change the validation rules for a "valid domain name" will do. I found that you have limited the length of a TLD to be 6 characters, but my punycode domain tld have 11 characters.
For your information, my TLD is .香港, Punycode = .xn--j6w193g
