Highlighting re-worded text

In recording, I have to stop, go back, and start from the beginning of the paragraph. In editing, I might start some editing, only to get stopped because I forgot I re-ran that paragraph again. 

It would be nice if Text could see that and warn me of a possible edits. So I would see something like thisL 

If a simialar word structure shows up within 20 words (for example), the first instance gets highlighted, indicating I might have to fix an area. 

If I take 2-3 runs at the same sentance, it would extend the 20 word view so I can catch that it took me 4-5 times to go through this. 

Having this text be more predictive will help me continue to edit without getting stopped, or frustrated because I have to do that part again.
