During development I wanted to see if
myapp/lib/AppInfo/Applicationphp got parsed at all and introduced a syntactically wrong statement, provoking an error.
Upon calling the corresponding page I see the top bar in a nice gradient from what I defined (orange) at the left end to the default (blue) to the right end. This seems reproducible with any incorrct statement in this file.
Is this an easteregg or is something trying to tell me somebody?
