you are right, that there are not so many example apps available, which use the MVC / MVVM pattern. Most of the examples are simple single-file demo-apps (like on the GeoExt website). Maybe a simple MVC / MVVM app would be cool and we had that for previous GeoExt versions: https://github.com/geoext/geoext2/tree/master/examples/app/simple https://github.com/geoext/geoext2/tree/master/examples/app-mvvm > > At the moment I am trying to build a pretty standard web mapping > application with a main map, an overview map and a layer switcher.

You can pass in the map or better a MapComponent, like https://github.com/JakobMiksch/HelloGeoExt/blob/master/app/view/main/Map.js, as config property of your own component. ExtJS will handle it like a member variable in your instance. If that is not possible for your whatever reason you can query arbitrary component instances with Ext.ComponentQuery.query (https://geoext.github.io/geoext3/master/docs-w-ext/#!/api/Ext.ComponentQuery). So a Ext.ComponentQuery.query('mappanel') might be a helpful command. Even I like it more to pass over dependencies as config.
