Some feedback/improvements ideas

What a wonderful tool. Thank you.

A few suggestions.

1. It would be cool as an ESL student to have the word explanation in different languages.

2. Have a quick global option to cut out the main common words such as "and", "if", "but" etc ...

3. Keep the edit fuction (the pen/delete) to the far left and next to the vocabulary word because sometimes you want efficiency and you don't want to look far left and far right.
