- Gray boxes around some controls, not around others
- Control layout. What's up with that sea of nothingness in the top right?
- No titles/labels for each odd grouping of controls
- I'm seeing horizontal scroll bars something in the tables, but the text isn't wide enough to need a scroll bar (Yosemite)
- OK button just kind of sitting in the middle?
- No cancel/revert function
- No standard window "close" button, just minimize or that weird "OK"
This is just a bad setting screen layout with really unpolished design. It looks like controls were just dragging and dropped in interface builder. I would suggest that you go and look at the settings dialogs other Mac apps like Mail, etc.
