Great for minor tweaks!
I find it extremely useful when I finish uploading a video and need to edit the description a bit, or add a thumbnail. What it really needs though is the ability to add and edit end cards. My computer is currently broken so I have a tough time editing end cards when I make a video. If you’d be able to add end cards to the app, that would be incredibly awesome and such a huge help.
