It is the very small piece of information which makes job lot easy by avoiding the need to query and search. It is generally easy to remember names rather than IDs. IMHO the same would apply for the VPC ID and Subnet ID in AWS.
AWS Management Console shows elaborate information about the EC2 instances which are part of the specified region and Account. Under the same details section, we can see the VPC and Subnet where the instance is placed. It would be great if the details would also show the Name Tag of the VPC & Subnet not just the VPC ID or Subnet ID.
Apparently the convention / notion of showing the Name tag is already used in the VPC menu where we apply the filter for the VPC.
It would help a lot if the same convention is also extended to EC2 Details Page.
