Matt Birchler, as he usually does, has put together a very achievable list of where and how certain aspects of the watchOS experience can be improved upon for the upcoming watchOS 7, with many of his suggestions geared towards giving more power and granular control to the user.
On improving interactions on the Apple Watch:
This one is pretty vague, but Apple should make a run through of the things you do on the watch and try to remove one tap from the process. This “one tap less” initiative would look at analytics for what people do on their watches most and would simply try to remove one tap from the process. We’re not rewriting the whole OS yet, but optimizing flows so people are more likely to do them on the watch than pull out their phone would help a lot.
Being an advocate of less is more, I occasionally review how I do, and how certain things are done to see if there’s any room to improve efficiency by removing at least one step out of the process, and I agree with Matt that there are numerous areas, if not all areas of the watchOS that would significantly benefit from less interactive friction.
