Your response is confusing:
“Yes, download manager pro already is an riched features plugin.” — What does this mean? Does it mean that there are already global settings available and I don’t have to add the PAID plugin, or are you just trying to say that (in general) Download Manager Pro is “rich in features… just not basic global-controlled settings?
“You may explore it.” — I have and have not been able to find where to set global settings for all packages and pages, outside of having to buy an additional 49USD plugin add-on. Which (again) seems ridiculous as it should be basic functionality for a “pro” level plguin to be able to natively control global package and page settings…
