When using data classifications and publishing an App Workspace to an App it does not currently maintain the classification. This should assign the classification to the entire app based on the highest level of classification and also all dashboards should at the least maintain the classification, which I am currently not seeing happen.

As an added bonus it would be nice to have some indicator at the Apps menu screen so you can quickly access which Apps fall into each category with color coding or another little icon as you have currently on the App Workspace Dashboard level.
