This is something we’re still looking for feedback on. We’ve gone back and forth here on the tools team about whether Classes should be in the Content Browser at all. Right now we’re leaning toward removing them.
Either way, I agree we should facilitate quick access to the source code from the editor where you can interact with classes.
We do have an experimental feature called “Code View” if you select an Actor in your level, you can expand Code View in the actor’s Details, and double click on class methods to navigate to the code, as long as the code was written by you (doesn’t work for Engine classes where the source isn’t available in Rocket.) Let us know if you check it out and have any feedback.
