The swivel LCD is another great feature, although not new, my T3i had it, but still worth a mention. One difference, think starting with the T6i, is the LCD is now also a touchscreen. Although I turned mine off because I don't want to accidentally change anything since a lot of things can touch the screen, from my hands to my nose... I'd rather use the buttons which have a lot less chance of accidental activation. But I know everyone has been conditioned to love touchscreens, so it's there, hooray. :-)
If you had access to the video editing pro level, then you must try DaVinci Resolve 14. Except for multi-camera editing, 3D editing, motion blur effects, and spatial noise reduction which are only available on the paid version DaVinci Resolve Studio, you can almost do any professional video/audio editing and color correction with DaVinci Resolve 14.
The second big draw is communication. The app creates a unified inbox for comments on Facebook and Instagram and messages from Messenger, so that you don’t have to bounce between different apps in order to respond to people. The app doesn’t seem to cover every possible messaging vector inside of Facebook’s services, but it sounds like a handy start. <<
