In iOS app store I can view the details of an app, and then identify the publisher, and then view other apps from the same publisher.
How do I view other apps from the same publisher in Windows 8 app store?
Assuming you are at the Metro UI:
Simply type the name of the publisher.
When the Search box appears, click on 'Store' [Key point]
Then browse the list of products by that publisher. In my example the publisher was jujuba.
