I needed to make a button where the action was a lightbox pop-up showing a stack.
Button factory pro solved this with an excellent result.

This add on has the possibility to tweak the theme layout for the button in so many different ways that it should serve all needs. A ton of different options, so many different button icons to choose from.

When I faced a small issue, the developer responded immediately, although it was a user fault.

This add-on is incredible in solving the issues it’s made for. It’s well worth the money. I for sure will buy it again on next project.
