Separate ongoing applications from individual case studies

[clynnes]

Summary

Some Application Topics are dominated by applications that apply to individual events. Those are valid "usages" of the data, and potentially useful for end users to understand how a dataset can be used, but it feels like they should be set off from the more general applications that work on a multitude of specific uses.

Basic example

Click on "Earthquakes": all of the applications are individual case studies. 4 out fo the 5 are related to ARIA, which might be one way to group them.

Motivation

Individual case studies are far more numerous than general applications, and having a dozen case studies that all show the same thing simply clutters the interface. So we need some way of grouping them that does not overwhelm the UI, but does allow users to drill down on specific use cases, which ARE useful in manageable quantities.
