Alternative routes browsing on iPhone

After a route was calculated on my iPhone, I can only swipe (left/right) through the alternative routes when the panel which is listing the individual stops is semi-coĺlapsed. So to actually compare the alternatives, I constantly have to swipe the panel up to see the details, then down to swipe to the next alternative, then up again to see these details, and so on. This makes it real hard to compare.

So please introduce the option to swipe through alternatives while the current stops panel remains expanded. Much the way it is already beautifully implemented on your android version on my tablet. Reduced screen size should not be an issue, since required screen space should remain the same as for the already expanded panel.
