I have now clocked a significant amount of hours designing slides in Apple Keynote. I love the program, but there are still a few annoyances that cannot be solved by adjusting your slide template or configuring other settings. Hopefully Apple will fix this in a new release (it has been a while):

1. Selecting what you click, not what you cover with your selection triangle
2. Make it easier to fill shapes quickly rather than having to go back to the inspector. I am always struggling with color windows and inspector settings
3. Enable custom toolbars, especially with options to center and align things. Yes, the smart drawing guides are useful, but not useful enough.
