I’d say reduce the “PRO VERSION” shoving in people’s face wouldn’t be such a bad idea. I don’t mind buying Pro Version of plugins; I just don’t like that whenever I tick an option in the settings and it suddenly grays out and say “NOPE! You need to BUY PRO VERSION for this feature ?? ?? :)”
Also, the “Generate Shortcode” tab is just a click-bait with a copy paste of the Pro Version features, which isn’t nice at all, the only way to find the actual shortcode is to go in the settings in the “Support” tab, where is the logic in that? Lol… This is just overkill.
Wanna make people buy your plugin? Don’t try to force-feed it to them, make them WANT to buy it, with detailed-simple explanation on the benefits of i t, not just a blunt list of features that most probably don’t know if it’d be ACTUALLY useful or worth buying, explain the benefits for example for SEO and responsiveness, just throwing ideas.
I was personally a bit disappointed by the free version, even if I was able to do everything without buying the pro through CSS tweaks, will probably buy it for future websites for clients.
