I am not sure whether this is the right venue for my question, if not I would appreciate if someone would send me where it would be more appropriate. I am currently updating the en.wikibook Dutch. As it is a language course it will only be really attractive to readers if it become sufficiently interactive that they can actually learn a language from it. Of course sound files are an important part of that and thanks to easier upload facilities at commons that is now feasible. There still are some problems, e.g. the smallest sound button I can make is woordenschat.
But this automatically inserts a break which screws up tables. If put into collapsible wikitables only a few can be added on a page, because then things get oddly scrambled. See for example the collapsible table "Vocabulary" on the right of this page.
But this is not really what I wanted to write about. What I really want to do is help learners with their necessary vocabulary memorization. Other websites seem to offer far better abilities than what the wikisoftware has to offer. E.g. at quizlet or memrise you can put a certain set of words to be practiced in a set of electronic cue cards that are then presented to a learner in a certain sequence that helps them memorize things. Would it be possible to add such functionality to the wiki software?
