I have a very minor feature request. In fact maybe it is something that is already possible but I'm not sure how to do it.
As far as I can tell, it is possible to export all of the words you're currently studying along with your added mnemonics as a spreadsheet-compatible file.
What I would like to do is export a single list. It's possible to do this at the moment but it doesn't seem to be possible to export any added mnemonics along with the list.
