I find that when I am learning vocabulary, I need to learn the word in it's unconjugated form first, then learn to apply the grammar rules later. It would be nice if there was a toggle feature than allows you to save the word as its lexeme, or if it could be automatically included as part of the word list.

For example (in French):
Français: Fais
Lexeme: Faire
Context: Je fais un gâteau.
