I have not yet pulled the trigger on this app, but I was shocked to find that a recent update added real Track Changes with MS Word compatibility. Am I seeing things? This lesser-known document editor is truly the first to bring track changes over to the iPad? The reason I haven't pulled the trigger is there are only a few reviews and some bugs/crashing are reported. But I wanted to bring attention to this and see if anyone else has tried it. I'm not sure why tracked changes are so difficult and why it's taken so long for someone to attempt this feature.
