Нужна помощь в правке плагина?

Здравствуйте. Может кто то помочь в правке плагина?
Суть вопроса: Проблема в том что нужно сделать отдельную страницу с таймером, основанную на плагине (возможно) https://github.com/Ticcix/download_page.
Нужно чтоб таймер был на ссылку вставленную через доп. поле и использовал шаблон плагина ( то есть клик по ссылке открывается страница с таймером).
На сколько я помню там что-то правилось download.php
Есть исходник когда-то работающего download.php
