To have like stats for list of popular words (and have analytics around it) which you often type.

[nishu-murmu]

This stats would include

1. The most repeated number of words that you've typed.
2. The words you make mistake the most while typing (this is the crucial one, for which I'm suggesting this idea)
3. The words you get correct almost 100% of the time.
4. so on and so forth.

Let me know your thoughts?
Was this suggested earlier, does this not align with your vision???
