Categories Level

Hi,

I am considering getting the pro version if it helps me achieve to attain the functionality required below:

-From the home page I want click on a resources page which displays all the categories top level (i.e. Music (5), Misc (3)) in WP Download Manager. (Am unable to do this with free version) How can I do this?

-Once you click on the category, it will go to the next level i.e. show music downloads.
For the display of the category downloads which some may not have files attached and no download button, can I display something like

Filename, Description of File, Download button? (Can also click within to go into file info)

Just wondering how I can do this.

Thanks
