I don't think it is completely necessary to have the light bulb button. I mean, people don't switch between light and dark all to often, more of what color. And even before that, many were complaining about it. I think it could be useful as a button to switch to any mode (Instead of having it at the bottom), and maybe switch it to like a color palette. The main reason I want this gone, is because it is kind of annoying almost every other day clicking on the button and getting blinded (As I use dark mode) and then having to switch back to dark, and then switch to St. Patrick's day dark as it doesn't maintain the old color you had.
