Enhancements to Vocabulary Section
I would like to offer a couple of suggested features.
1) It's great that the vocabulary section lists all of the words that I have learned. However, I think it would be even more useful if it included a column, which listed the English translation of each word. As of now, I need to manually click on each word to know what the translation is. This is tedious if I am trying to look at the words that I'm having trouble memorizing.
2) It would be useful if we could export a PDF version of the vocabulary listing to study (or perhaps generate a printer-friendly version) of the vocabulary. This would need to include the English translation as a column for it to be useful.
Keep up the great work on this awesome program!
