The plugin enables user to add buttons with advanced settings in Gutenberg editor. This button is similar to default Gutenberg button but it has many extra settings.
It is possible to add fancy hover animations such as grow, shrink, wobble, float… There are also settings for hover background, hover background transition, border radius, button size.
It is possible to add custom styles for button or button’s hover state. It is also possible to set the button to open in new tab.
