kai is inspired by LaughingQuoll's Maple tweak series, and Apple's Air Power design. kai was built with inspiration from this. However, the main reason I made kai is because the Maple series does not work with notification grouping tweaks like Axon and Grupi. Additionally, kai features a wider range of customization options.
