WordPerfect Office, since version 9, has a very nice timesaving feature called RealTime Preview. When choosing specific font from the dropdown list, the selected text is already reformatted and displayed using that font. This applies also with other types of formatting. And because the update is instant, you can scroll throughout the font list and see the text "morphs" into different look and finally choose what suits you best. This is not like in other office suite, where you need that many repetitive clicks because every time you change the font, the text just looks ugly and you have to repeat and repeat it again.
Half a decade later, Office 12 has Live Preview, which is basically the same thing.
