Hello,
With the above shortcode I got the answer for my 2nd query, but still not able to get the answer for 1st query. I tried to modify the code as below to show the description of the each package below title but to no avail:
[wpdm_all_packages thumb=1 items_per_page="50" jstable=1 order_by="publish_date" order="DESC" cols="title,desc,file_count,download_count|publish_date|download_link" colheads="Title|Date|Download::155px"]
