Thanks! I really like to go all out when I create a readme haha The main reason I made the app was for the darker than dark dimness functionality as my eyes struggle in a dark room even at lowest brightness! As for the night shift slider it is mainly a bonus feature I added in which I thought could be useful for anyone that may find night shift a bit too strong at times (e.g. during the day). Ultimately, most people probably wouldn't need it but for people with sensitive eyes like myself I think its useful :)
