Why doesn’t this plugin have more users?

I have tested the plugin extensively (custom fields) with both Kadence and Greenshift, and it works perfectly (except for the repeater in Kadence). The plugin is also lightning fast and has a super pleasant user interface. The only confusing thing might be the name; instead of just CubeWP, it is called CubeWP framework, which makes it seem very complicated and might lead many to think that it offers more than they need, whereas the plugin actually works easily and smoothly.

Is the plugin still actively maintained?
