- Remove search box until we have decided how to approach it;
- Show apps pagination dots;
- Dismiss app list UI on escape or click on non-app and non nav dots;
- Defer widget showing further until apps are loaded by webui;
- Add a container div to limit apps page height so that the gap between apps icons and nav dots are not too big;
- Passing bounds when requesting app list widget to avoid resizing;
