So you've saved a couple of meanings, pronunciations or sentences... Now what?
Go to the Vocabulary section in the menu (or click on the stars in the top panel), and you will see all your saved words ordered from the most recently added ones, in the original context.
You can click on any word you see there. You can even star any word, if you want to.
There are 4 icons above the list, looking like this:
The first three tell you the ordering of your saved words. You can order them from the most recent, from the oldest, and randomly. “Oldest” or “random” work best for memorizing vocabulary.
Here's how I recommend to do it. First you should order the words any way you prefer (e.g. from the oldest), and then do the following for each sentence you see:
When you remove a star from a word, it is marked as “learned”. You can access learned words by using the icon or by clicking the same icon in the top panel.
Your learned words are highlighted in gray. It's a good idea to review them from time to time.
