Synapse: Framework is a full comprehensive UI remake and minor redesign of every single era of Synapse X, it brings back every UI with all of the expected features. Uses methods that allow it to work as a custom UI on any executor. And allows you to theme to your hearts content with a simplistic system known as the theme control panel. It brings back Synapse V3, X, 2017, and Synapse Blue, all with the expected functionality your thinking of. Some features are unfinished but the sole dev "Snooped" is hard at work almost every day to continue on.
