APPcenter

• Good products has Appcenters like Apple App store , Ubuntu App
  center ect..

• by using those centers we can discover thousands of apps in various
  category's.

• When we consider about drupal, if we want to add module we need to
  download that module from: http://drupal.org/project/Modules or http://drupalmodules.com
  and install it.

I am trying to propose convenient solution for module installing

possible implementation

1. Develop separate module to access and browse module-galary through Drupal.
