Hi, some suggestions for the vocabulary page -
The ability to export a vocabulary list, or create a printer-friendly chart with English and target language translations
The ability to see conjugations without clicking into the word. There's a lot of white space on the right, why not use it?
The ability to search for words by its English meaning, not just the target language spelling
Implementing these - especially the first one - would, I think, make our experiences a lot easier!
