Recycle bin funbox

[KitKat20255]

If you have input history on, and color coded words you'll see the words that you're struggling with. A good practice it's to focus on those words in particular. Weakspot in funbox will focus on the characters/bigrams that you're struggling with from what i understood, but i think a better way would be to take the red words and make an individual list of let's say max 1000 words or more if the space it's not an issue, and the list it's editable.
Let's call the list "Recycle bin". When you activate recycle bin/weakwords mode, words from your bin will randomly generate a test. Once you go over one of the words several times and it's speed it's not in the red anymore, it will be removed from the bin.

Make Zen mode compatible with this at least for english, so at the end of a text you type, the words will be compared to english dictionary and the words that are detected as real words when compared to the dictionary, will be added to your recycle bin list if they were in the red at the end.
