Some opinions on trackpads: - Tap to click should _always_ be turned off; it's bad and it should feel bad - More apps should take advantage of multi-level clicking
Personally, I love Apple trackpads so much that I use one (Magic Trackpad 2) when my laptop is docked to my monitor. Mice just don't do it for me anymore on macOS. They just feel clunky.
Edit: Also, Apple should promote the "three finger drag" Accessibility setting to the Trackpad settings. It's far superior to all other drag-via-the-touchpad options, IMO.
