In the selection where it allows you to select Simplified or Traditional, I'm a little confused as to some of the functions:

- For characters that have simplified and traditional forms, are they counted as one character or two for purposes of "Characters learned"?

- If you went from, say, traditional to "both", does it add all the simplified characters that are in your vocabulary at once?

- Is there some way to have it add a form as secondary, after the primary form moves into the retention stage? Or is that what "Simplified and prev. Traditional" (and vice versa) do?

They are counted as two characters for "characters learned".

It only starts adding the simplified characters alongside the traditionals for the new words you add. You can go back through lists you've already done to pick up the other forms of things.

No, it'll try to give you both forms at once. They'll space out from each other a little bit. "Simplified and previously added traditional" just means that it won't add traditionals, but will review ones that you've already got.

I had a similar issue. When I first studied Chinese, I was learning Traditional forms but Simplified are much more useful to me at the present.

At the beginning, I chose Simplified but a couple of weeks ago I thought I would switch to "Both". I have been extremely happy with the results. I very much like how you have set up learning both forms. I faced the switch with a bit of fear because I thought I would mess up my Skritter State but I have no regrets about doing so at present.

Originally I wanted a feature to allow the slow introduction of Traditional forms of Simplified characters I had already learned, but I realized that I could easily achieve this by re-introducing the character list I had already studied in Simplified form. This way I could control the rate of the traditional forms being introduced.

Another issue I had was that Characters learned no longer helps me measure my progress against a meaningful goal but just measures progress. The pat-on-the-back from the present approach is great, but I would like something that measures how much of HSK A I have learned (characters and/or words). At first, I could just use the progress in the word list, but now I have introduced other sources and really don't know how close I am to finishing HSK A.

I small quibble but it would be nice.
