I'm sure this has been discussed before, but my search skills leave something to be desired. So, I'll go ahead and ask.

If you have numerous lists open for study, and you hit the manual add button, what's the mechanism by which Skritter chooses which list to add from? I've got a couple dozen open lists right now, and it cogitates a while before adding a new word when I hit the green "+".

It adds the top ten lists among the ones you are adding from, starting randomly and going around in order. The best way to control which of the ten are added is to pause the ones you don't want to add from and have the rest being added from, or to study a single list by itself.

I'm not sure... Its adding words from outside my top ten lists for sure. My admittedly lackadaisical observations are that the next word to be added comes from the list on the bottom.

Looking at the code, it looks like the lists on the study nav page are ordered by when you last interacted with them, whereas the study pages fetches up to twenty lists in no particular order, starts at a random place for each Flash session, and then adds one at a time from each of those lists.

I wonder if caching these lists would help performance much. What do you think, Scott?

Hmm, oh yeah the code for the study nav has changed but the code for actually adding words hasn't. I'll tweak it so that it works properly, and look into doing some caching. That will probably be more helpful with some of the upcoming tweaks to how words are added from lists.
