I would like to try build my first WP8.1 app and I have a problem with CommandBar in Hub. I want to add different bar to all HubSections but I don't know how to do this :/ I tried to use SectionsInView (like here) but the change of CommandBar items is sooooo slow.
The second question is how can I make transparent CommandBar in HubSection? HubSection contains ListView. Now, when I try to do this, ListView bottom margin is changing and I don't see ListView under CommandBar (I don't know why...). Look at picture.
The third question is how can I change AppBarButton color when I'm pressing it?
