After trying some more search terms combinations, I see two mice now from Microsoft that resemble the Magic Mouse. But I’m really struggling to find anything else?

What I’m not finding is my dream mouse, which would have an ergonomic design, lots of customizable physical buttons like my Logitech mouse, but with an additional 360° scrolling input (either a touch sensitive area or a trackball (sized large enough so dirt clogging wouldn’t an issue)). It just seems like an obvious product to me; I’m surprised it doesn’t seem to exist yet.
