I recently purchased a brand new MacBook Pro 2018 13" and I was hoping to find Lightroom CC to be a bit more performant. But it's sluggish. Scrolling photos and general operation is just not as fast as you'd imagine it to be on a brand new computer. Other apps are speedy and feel fine so it has to be Adobe's codebase for the reason why. Lightroom CC should be fast seeing that it was rebuilt from the ground up. Please, please, please spend some time ensuring its fast and responsive. Don't keep piling on features and make it more bloated. Speed and performance are so high on the list. Please Adobe, don't make the same mistakes as your other software.
