Validate Interface Builder layouts

I just found an option that is probably obvious to many. When you adjust your localized interface layouts using Interface Builder, you have the chance of validating the layout (shift-command-v brings up a dialog). You wil be notified of cases where content is hidden or clipped, or other similar troubles you might run into while stuffing your translations into the narrow spaces set-up for the English version.

So, my advice is to use this feature whenever you check your .nib files, to make sure everything shows the right way.
