Right now, if I added a large swatch of contiguous code, the stage feature in Xcode is all or nothing — either I stage all the changes or I stage none of them.
It would be a better UX if after spotting the isolates changes within that swatch that are final if I could select them and stage them. This way, it would be easy for me to easily green light all the changes I know are production ready, and then when I'm done, clearly see those which are not and easily be able to hone in on the changes that require some more thought.
