Hi,
Not sure how hard it would be, but could you possibly add a priority to lists that are active?
I know at the moment by default as skritter is cycling through it usually picks 2 or 3 words before moving onto the next list. But would it be possible for some to pick more or less? i.e. I like to prioritise working through my textbook vocab but also like to slowly drip in some hsk5 words. I can do this currently by remixing my textbook and having it in twice, but I also have a wordlist with in-class words I like to do at the same time. And as I'm always adding to it, its a bit hard to keep remixing?
Also side note, and perhaps I shouldn't be mentioning it here, but theres a slight glitch with the ios app when adding words. If you select the textbox to add words it always seems to highlight it instead of allow you add type in words. Not sure if it's just me, but i've tried it with a few ios devices and get a similar result.
Keep up the good work!
