On today’s office hours the topic was “expressions” and an audience member asked, generally:
“Where are all the places you can use expressions, and, can I change the names of views and display values using expressions?”
On this general subject, I had put together previously an app that demonstrates creating custom labels and display mechanisms in such a way that you could have an app handle different types of “app-level” solutions. In essence, it’s a meta app of apps. Not an app launcher, but rather, a single app designed to allow different groups of users to manage different taxonomies of information. It has many, many expressions driving the entire UX.
Here is a doc that describes this process as well as a link to a public sample that you can copy and customize. Let me know if you have questions or feedback!
