Not at the moment, no - we're a little reluctant to do it totally automatically because it's really hard to capture intent effectively with flashcard history; people look up a LOT of words they don't really consider themselves to have looked up.
You can however dump all recently looked up words in history to your flashcards via the History screen.
I hear that, although I'm not sure how accurate it is.
Could you offer a way to have a word added to our flashcard deck with a simple click on a word we have looked up? I'm just looking for a simple/convenient way to add words to my/our flashcard files.
You can tap on a word in the history list to view it as a dictionary entry and then tap the + button to add it to flashcards as with any other dictionary entry. (And scroll through the list with the arrow buttons at the top)
We might add a batch mode to that screen at some point to let you tap on a bunch of words to select them and then add them all to a category at the same time; would that help?
Adding a batch mode would make a big difference. I/we spend a lot of time adding words to our flashcard files, a batch mode would be a big time saver. Flashcards are an integral part of our study/learning process. (How many people have purchased FLASHCARD upgrades). Just making that process easier/more convenient would improve the process.
