Group passes

[ligi]

When a group wants to check in it should be possible to swipe between grouped passes for an easy process - currently the user has to often switch between list and pass-view.
Idea for grouping - if passTypeIdentifier and relevantDate are equal -> the passes get grouped

This should have a high priority. When you are in a queue, probably pressed for time, ease of use and quick responses are essential. Speaking from experience here. Having to go back to a different view and selecting from a list again is a recipe for delays and stress.

You are right - the problem is finding a good UI for this - the grouping must be transparent to the user - currently I am working on a concept that there is only a list left where you expand the pass entries - no more list<>detail switching - but I have to get that right before releasing - a lot of people use the app currently and I cannot get back and forth too much

How about just being able to swipe left/right between any entries in the current list? Grouping would be nice but left/right is already very useful.

Not sure but I think this can be closed since #212 fixes the navigation issue.
