iCE shows Lookup, Favorites and History lists in the main window.
From the main window, click the Lookup tab to lookup words using Chinese (simplified, traditional), Pinyin or English. This "reverse dictionary" lookup lets you find exactly what you need from the 100,000+ entries.
Click on the Favorites tab to list the words you've tagged with a star.
Click History to see a list of words you've seen recently. This is a handy way to find words you've seen, but can't remember.
Loqu8 iCE maintains two words lists; the Professional Edition keeps three word lists. Lookup shows the words you requested. Favorites displays the words you've tagged with a star. History contains the words you've seen recently (Pro only).
