Hey PH
States of the artboard is a Sketch plugin for creating different states and switch between them easily. Just like layer comps. I created it since it was missing for me in the design process and couldn't see why not to have it in Sketch as well.
Buggy and unusable. Getting stuck Sketch 3.8.3 on any state switch. It seems there are more efforts to promotion, not the product. NOT RECOMMENDED. Layer Comps from Adobe at least work. Uninstall and forget. Thanks for try. GG
