Disable selection mode and search when there isn't any content

Description
If I don't have any videos, selection mode isn't useful. Search isn't useful either, in its default "local" mode. This is a particular issue when a user is trying the app for the first time, since they might want to explore the available functionality, and it's a bit of a downer to have features that aren't useful.
It would be better to disable these functions when there isn't any content, and to make their buttons insensitive.
