What is the best, most interactive and best UX design for a "book recommendation plugin" in general?? It´s for an online community for digital professionals I´m creating that´s on a WP Listify theme.
This highly depends on the features you'd like the plugin to have. So it's hard to answer just like this.
We can hop on a call and I can see if I find something that suits your needs or suggest ideas how you could solve the problem.
Cheers and make today the day!
