There are multiple informative commands available and there are many of them which are missing too. Some available commands are:

• templates
• path
• dot
• list-dependencies
• query

Some missing ones are:

• list available indices (Hackage/Stackage)
• list packages in an index
• list available snapshots/resolvers for an index (stackage)
• list packages in a snapshot

We can have a stack show command and incorporate all of the above under subcommands of show. That will also reduce the top level commands and make the commands better navigable.

We can split off implementation of the missing ones listed above in a separate issue. Those will be really useful to have.
