I quote
“Create unlimited menus
Lots of customizable settings
Insert anywhere on your site using SHORTCODE
Built-in Animations
WYSIWYG editor – Live preview
Easy positioning options”
I mean that you should state clearly in the description that all the features are only for Pro version. It’s not a problem to buy a Pro version, but you should state clearly what you get for free and what you don’t, otherwise I’d consider it “misleading”.
Installing a plugin is always a risk for the site but one takes the risk for a little more in exchange, whereas in this case you install it just to have a demo version in your own server. ?? no offence, it’s just my opinion
