Good, but cannot fullscreen

I just downloaded this app and I really like it! It literally functions like YouTube on the web, except I don’t have to open a browser :)
However, I am unable to view the video in fullscreen mode — the only option I can use is “theatre mode” which is honestly a little annoying (who even uses theatre mode?!) Please please please add in a fullscreen option! I’ve checked the settings in the app in case I missed something but there isn’t anything I can do to fix this!
Other than that, this app is great and I recommend it to everyone!
Oh yeah, I’ve just thought of another thing — it would be a sweet feature if we could choose to get notifications when somebody comments on our videos or when someone replies back to our comments!
