Add some link or other interface element to provide the "Sort by alphabet" function
Such link would reference something like:
When alpha is provided the html template must also take care of providing the alphabet based links instead of the page numbers on the navigation section.
Update the controller code to handle the alpha parameter
File: base/modules/packages.py (* this is the more complex part*)
Extended the get_applications_list function to support the alpha parameter or create a new get_applications_list_alpha, this will require new SQL and related code.
