Configuring Eclipse to look exactly how you want is a tough job I've found, therefore I'm not going to attempt to do this myself.
I'd like to 'zoom out' of the Package Explorer side bar? You see, I like only having my code on the screen with a small section for the files in the project - however I can never see the full path of the file or package I'm currently in because of this. Is there a way to keep the 'main screen' normal, but zoom out of the Package Explorer by about 50%?
