The 'local' and 'admin' dbs are different than user created dbs but it is not clear in the shell.
For beginners it is confusing.
I wanted to delete all dbs but didn't remember what dbs where created by mongodb and what will happen if I'll delete them.

Is it possible to separate between them in the shell?
Options:

1. Add an asterisk near the name of a special db

• admin
• local
  mydb1
  mydb2

2. print a title for the special dbs and user created dbs:
system dbs
----------------
admin
local

normal dbs
---------------
mydb1
mydb2

3. show dbs will show user created dbs and show sysdbs will show the special dbs..
