Use different plugin names for free and pro version

As others have stated we get security warnings when using the free version due to (already fixed) security issues in the pro version. The free version currently has version numbers around 3.* and the pro version has them around 6.*. Since you’re using the same plugin name for both you’re unintentionally provoking confusion for security software and users. Hosters will warn about using the free version and some even will block / delete them.

(My situation is that a customer has two websites, one with the free version and one with the pro version. The hoster complains about the free version even if the fixed update was already installed. They offer a “Scan + Repair” function and I fear they might delete the free plugin and thus break the site.)

So my strong suggestion is, that you use different plugins names for the two different versions. Basically all vulnerability databases depend on a unique plugin name. This could be download-manager and download-manager-pro which makes it obvious, that they are different plugins. Other plugins do this as well (i.e. Solid Security, Yoast SEO, etc.).
