You were talking about device mode pages in your original post, now you have changed your beef to activity mode pages.

Activity mode pages definately do matter, however the setup cannot read your mind as to exactly how you want your activity pages organised. It will have a go at a basic layout, but it is up to you to customize it to your liking.

It would be nice if everything was set up perfectly for everyone first go, but it's not exactly feasible with so many different combinations of equipment for one activity.
