We want to add several apps, one for each resource type, to make it clearer where to go to when looking for certain resource files. For this, we need filters that can be configured presumably together with the actual app definition and which make sure that all an app shows are resources of a particular type.

So this is analogous to the "JCR" browser app, where we configure the workspace we want to show in the app. This would allow us to have a "JCR website" app for browsing the "website" workspace, a "JCR config" app for only browsing the "config" workspace, a.s.o.

If possible, write the filters in a way so that we could also use them to filter a list view, as there are plans to add such a view later. However, these plans are vague for the time being. So if that's not feasible now, please focus on writing filters that can be configured in an app description.
