In all fairness Amazon's Management Console has come a long way. And I use it regularly. But, and this may be because of my history using Elasticfox, I use Elasticfox-ec2tag faithfully. In fact, it's always the first tab in my browser.
With Elasticfox-ec2tag I can easily view and manage my EC2 servers, AMI images, Security Groups, EBS volumes, Elastic Load Balancers, etc. With it I can easily connect to any of my AWS accounts, and any AWS region within each account. I really like that you can customize the columns, both which to view and their order. Another great feature it supports is the EC2 name tag which is also supported by the AWS Management Console. With this I can assign a meaningful name to each instance and view that name in both tools.
You can download the latest Elasticfox-ec2tag Firefox plugin (.xpi file) directly from Amazon at http://elasticfox-ec2tag.s3-website-ap-northeast-1.amazonaws.com/.
If you haven't used Elasticfox-ec2tag I would highly recommend giving it a try.
