Prefered new features

I wont write about 3 new features which could be really helpful and i think they are really simple to implement:

1. Open new document without adding him to project. Many times happens that i need to reformat some code and see syntax but dont wont to save it.
2. Highlight distinct files between current and selected branch (mostly master). It is vere helpful to see which files were changed by me in my branch. I usualy dont commit changes so i can see this files blue,green or red (modified,added, created but not added to git) but this is obviously not a good idea.
3. Allow open class by service name defined in services.yml. Because it is boring to manualy search in services.yml :)
