I am a little confused as to why having fast code access via the editor is even important.
I’ve been working quite a bit on my ue4 project, and I dart back and forth between three programs constantly
- 3ds max
- ue4 editor
- my own chosen c++ editor
I’ve never once thought it would be necessary or even convenient to see the c++ while in the editor when I have all my classes open in a dedicated editor.
And I cant imagine the other project members needing this option since they probably wouldnt be the programmers
For me the whole point of the editor is to remove the c++ awareness and replace it with far more user friendly GUI systems like blueprints
One thing that I think would be useful though would be a way to get a list of all blueprintcallable functions from any class, as that would be the only thing relevant to the editor anyways 
Just sharing my thoughts hope you enjoyed the read
