Feature Request

I've been finding the "Test" feature on the "Progress Chart" page (at http://kanji.koohii.com/progress) extremely useful.  I find that if I review the kanji three or four times in the the 48 hours after learning them, I remember them much better.  The problem is that the "Test" includes all the kanji in the chapter, regardless of whether those kanji have been added.  This means that to be able to use the "Test" feature, I have to have completed the entire chapter.  Many of the chapters are difficult to complete in one go, and I would prefer to be able to work 5-10 characters per day rather than 60-90 every week or two.  Is there any way the "Test" feature could be modified to include only the kanji in the selected chapter that the user has added to his/her list through the "Manage" page?
