Twitter for Mac fullscreen and whitespace

Here’s Twitter for Mac running in fullscreen on an iMac. An extreme example perhaps – I know there aren’t many people out there using Apple’s most popular desktop model.

And just so we’re clear, here’s the same screenshot but with whitespace colored red.

Also, an unedited screenshot of the fullscreen compose view. I did not add the black myself like I did the red color above. This is what it really looks like.
