"Great Asset! Great Dev!! ... This helped me so much to replicate a layout users were creating via a web portal. I ran into an issue with text heavy load times, so I reached out to the developer, who had a work around for me the same day, and an actual patch to the asset within a week.”

“It made my life so much easier! … This allows you to build nice interfaces using just two components with many settings. This is a lot easier than understanding a bunch of standard Unity components. Recommend!"
