Why dont all my Apps show on Chrome Webpage, when I press Apps at top

When I click Apps at top left in Chrome it brings up a page of just Googles own Apps.
Not ones I have installed too, including Pinterest, Videostream, Chromecast, Send by Email and more.
Should it not show all my Apps?
Wanted to add Videostream in particular.

You have to Add the desired site, (main page), as a 'Page' or 'Shortcut':

Thanks but Add to Desktop is greyed out.
Should they not appear automatically then when I click Apps at top left?

Some do and some don't. Chrome will create the link on the New Tab Page if the Add-on behaves as an App, others are merely Extensions.
