This control is deemed like the showcase control in windows phone. Its simple, its elegant and non of the other platforms have anything similar. Its been described as being synonymous to a magazine cover. Dave Crawford’s design talk is a great intro to this
Most Modern UI stock templates use a very typographical layout. Its all textual with no branding samples in sight – unlike real life where branding is a foremost part of the experience. Here is link to dev center’s article http://msdn.microsoft.com/library/windowsphone/design/hh202892(v=vs.105).aspx This article talks about various aspects of using panorama control etc.
For myself, the first time I was tempted into using Panorama was after playing with the new Facebook Beta app. This app divided windows phone community by marking a significant departure from textual nature of panorama. So far in Cineworld app, I had restricted myself to Pivot but I could see myself using panorama..
Branding:If an app requires specific branding, its best to create a user control that provides the option to set Brand logo and optional text messages. One isn’t restricted to a two line header on each page
As you can see, instead of excessively large page header, the customised header is very compact and since its a user control, we can consume it across other pages within the app. So what can we do with Panorama, well it exposes a TitleTemplate. We take the UC and we shove that in TitleTemplate. You can further customise the HeaderTemplate to change how panel headers look like.
I am definitely not saying you should do what I did. However what I will state is that Metro or Modern Design is really just about good design. Just because stock templates do it one way doesn’t mean no one should do otherwise. Kudos the designers of the new Facebook BETA app for doing something different.
