For high fuzzy matches in translation and review tasks, where, for example, there's only a difference in punctuation between two segments that have already been confirmed, if the user makes an edit to one such segment, it would be nice to get a warning indicating that there are other segments in the file(s) where the same change may be needed. 

For example, if there are two segments as follows:

Segment 1  -    El depósito debe llenarse diariamente

Segment 500 - El depósito debe llenarse diariamente.

and the user decides to change "depósito" to "tanque" in segment 1, a warning could let the reviewer know that segment 500 is a high fuzzy match to segment 1 and probably even offer to propagate the change (a fuzzy match repair?), letting the user decide.
