Yeah, those are some of the best features on mobile which aren't available on PC. If you don't have a mouse with a good clicky wheel, selecting tools really isn't very well optimized on PC. Try it on the last wired Apple mouse with the tiny scroll ball on it - no clicks and *really* a PITA to select tools. I replaced one of those on my secondary PC with a "slightly broken" Anker mouse with a good clicky wheel and it's soooo much better. And I started playing on PC and play Minecraft which uses a similar system so I'm used to this setup.
