Update (6th June 2012): The new options box is now live.
The options box is soon to undergo a major refresh. The current options box was introduced along with superoptions, and while its simple division of options into ‘Basic’ and ‘Advanced’ categories made sense at the time, it has become increasingly crowded as we've regularly add new features.
The current options box
You can see a preview of the new options box below. New features include:
options grouped conceptually into tabs — text and images, multimedia, social, and so on
less scrolling — you’ll only need to scroll on the columns tab
detailed option descriptions
easy dragging — move the box around by dragging the semi-transparent frame
visibility of unavailable options — if an option isn’t available (for example, because the current column is too narrow for it), you won’t have to guess why
