After hours of testing several plugins I decided to use WP Download Manager for a current project, because it give me more freedom to manage variables and build my html structure. However, is possible to improve this part throught remove tags limitations into the existing text fields (I'm talking about Templates section). This means the possibility to have all tags available in all textareas.
About Add/Edit Section would be fine to have a couple of extra-field text input for assign them to any needed task. IE, now i'm needing to have one more text field to place the path to file's thumbnail (the download is a heavy weight image).
Well, only these little requests. Hope the developer considers to add them.
