First, I would like to thanks Dirk2718 and vaniaspeedy, you guys are really good at programming. I really appreciate your work. Keep on the good work!
1)I'm not sure if the Toggle function is like a sub-folder function in windows explorer, that allows us to show/hide some documents?
2)I have met some problems on the debug files (and the original, too). It makes my Kindle restart when I click on it. (should I create a new debug file, or change the .sh file?)
I'm not sure how it works, should I edit the config file in profile 1? I add some file name from the books, but fail to hide it. (i.e. nothing change)
