APPALLING!
The plugin itself doesnt work, it asks for an "overlay image file" and an "overlay config file". It doesnt come with any "default" options, in case you have no idea wtf it wants. It's just assumed whoever wants to use this is an uber-1337 coder who can figure it out.
Theres a video "tutorial" but its starts with just a finished product, and just a lot of talking, no showing from scratch how to set it up. A tutorial should start from the beginning and walk you through every single step. There is a "tool" to help apparently create presets, but no explanation of how to use THAT either. Again the tutorial starts off with a finished product so no good.
Raised as an feature/issue on github, and the dev replied to state that ANYONE WHO WANTS TO USE THIS PLUGIN IS EXPECTED TO KNOW HOW TO CODE HTML, JAVASCRIPT AND CSS!!!
