Development:Editing Nibs

Follow the general guidelines in the Aqua Human Interface Guidelines about positioning controls and center-equalization, with exceptions as noted below.

• Be sure you do not break the focus and tab cycle (both normal and Full Keyboard Access) when adding or changing controls in nibs.
• Make sure the initialFirstResponder is correctly set to the first element which should have focus (even though Bug 327203 currently blocks this in prefPanes).

• It's important that all prefPane windows have a width of 595 px (since they will be forced to that dimension in the actual prefs window).

• Application names in nibs should be capitalized. Any quotations should use curly quote characters. Omit the comma before the last item in a series.

• website, web pages, Internet, URL, Location bar, pop-up, text field.

When modifying nibs, keep the following template in mind (from discussion over Bug 308942).
