It'd be great to use the information that's on a company's website to the max. When I add a contact I always add the company first and then link them. But things such as the "about" section, or the company e-mail adresses or phone number are all usually on the website but are not automatically fed in Nimble.

Another thing that would be awesome to have is the person's description on the website. Quite often when you deal with executive level managers (or with smaller companies), there is a full description / bio of a lot of employees on the website, right there for the world to use (and sometimes even phone numbers or e-mail addresses!)
