Adding things that will be used by TAPL.
1. Adding Ctrl+W to open widgets
2. Marking a UI element with shortcuts_and_widgets
id. Example of usage: we want to be sure we are in all apps.
A somewhat paranoid way to check this is to check that
apps_view is on, and workspace and overview_panel are off.
However, workspace is always in the hierarchy. We use
shortcuts_and_widgets instead.

We only show the back button when adding the floating view to the
drag layer if it is already "open". A couple of floating items
(folder and options popup) added first then set mIsOpen, causing
the back button to not appear. (We have to check that it is open,
and not just on the drag layer, because we want to get rid of the
back button when changing to some states such as spring-loaded. If
we only checked if the view was present, it wouldn't hide if one of
the floating views such as folder or shortcuts was animated closed.)
