Comment 1 for bug 593209

What would be really cool, is if you could right-click on the buttons themselves, and upon doing so, a context menu pops up that allows you to immediately adjust this duration. That way, as you watch different types of videos, you could immediately adjust the skip-durations to your liking for the type of videos your watching.

That may be wishful hoping, but the idea of simply putting these options in the preference menu is something I'd expected to already be.
