I don't think they'll add in much to any more customisation. It messes with their whole approach of just building lots of cars and matching them to people. When you have lots of different combinations you move to a custom order system like most manufacturers have had. If you look though at companies like Mercedes / BMW the number of options seem to be getting cut down and moving more to packs of options. I suspect they see the advantages of the Tesla way and are looking to simplify their process.
So from what I've seen when you are stopped with brake pressed it'll appear so then you just swipe on the screen vs using a stick to change. I don't think this is too bad. You are right you wouldn't use the auto direction select here, you can just pick yourself. I believe you can turn off the auto direction select which I suspect I would do, I just don't like that idea to be honest.
It's really the indicators on the wheel that puts me off. Over time you might get used to it and be able to handle it but I don't think could ever say it's better than the solution we had before of just having it on a stalk that doesn't move with the wheel. This didn't need re-inventing. I think the only reason they've done it is they don't make the stalk and buy it in from Mercedes so just less parts to the car overall.
