I really like the feature where asterisks are put next to the words in the dashboard to show how important these words are. I really like knowing if a word is in the top hundred or few hundred most frequent words. I have been noticing, since starting to get back into Russian, that all of the words that I thought were really important seemed to be stuck down at one asterisk. It turns out that I am right, and this is a bug in the website. Check out the following video.
I start by showing a word in the vocabulary page which has four asterisks. When I go to the lesson page, it has only one. I show it again for another word, and then I scroll through some very important Russian words in the lesson and show that they all have only one asterisk. This problem also appears in other languages.
