Integrated Certificate Service
Buying, managing and configuring Certificates is a hassle. It would be great if you could cut a Certificate from the Azure Certificate service directly.
Optionally have it adjust your configuration to make the proper changes for it's use.

Wildcard if possible.
I totally agree. Having to go find a third-party CA, figure out which type cert to get and then try to get it uploaded into Azure is a huge pain. In fact it's a brick wall for some site creators. Being able to create a certificate right from the portal would really help streamline the process and would increase security since it would cut down on mistakes that happen with today's complicated process.
