There are perhaps many things i would like to be able to control with the camera but for example using the follow hearthling i woud love if it was possible to do this with your own free angle and zoom when using follow hearthlings. normaly it’s very far away and not the angle i’m looking for.
It would be pretty cool if you could for example follow the hearthling down in town zoomed in pretty close and have an angle that makes you see a bit infront of him or perhaps have a camera that spins slowly around the hearthling or an object.
If it would be possible to for example place an object in the world if it’s required it would be cool to do that for a spinning camera.
a slow moving camera for more precision
Get the view from within a hearthlings perspective would also be quiet cool to get.
Hide UI
perhaps when using space or middle mouse to drag camera hide the cursor thingy since it would look a bit odd when recording to have it there 
Alt+Z still have this visible
Many ideas and many more could come 
If you feel like you wanna give it a try and have time for it feel free to do so
