Yeah, I noticed that the little symbols aren't very dark. If I can help you out, just let me know!
[doublepost=1477337781][/doublepost]Oh, and as for that iCal icon...
Maybe we shouldn't change it. Maybe we should just foxbox the Calendar web app from iCoud, just like has already been done with Notes and Reminders. Then we could change it to an icon that doesn't show the current date. This way the Calendar would still sync with iCloud.
[doublepost=1477339983][/doublepost]One more thing... If the Extras file is found in the Carbon framework, wouldn't it only work for Carbon applications? I have found that it doesn't work in iTunes. Besides that, it seems to work in Cocoa applications. It works on the Leopard Market, and I know for sure that is Cocoa. Strange... Well, glad it still works!
EDIT: After looking through the Cocoa framework, I found no files containing user interface elements.
