This is a great time to plug the project I'm working on, then! I'm in my third semester of Greek, so I decided I wanted to make a set of Anki flashcards for every word in J. R. Cheadle's Basic Greek Vocabulary.
Then I realized that I wanted to put in etymology tags, since a Greek word is much easier to learn if it has a Latin or Sanskrit cognate.
Then I realized that that's a much bigger project than Anki can handle if I want it done thoroughly. So I'm creating a spreadsheet that will eventually become Greek Vocabulary for Philologists. It's essentially an etymological dictionary, plus cognates, for the first thousand to fifteen hundred words. After that, I might make Latin and Sanskrit versions...
