It looks as if both Eno and igoldsmid have replied in that thread giving feedback after your last reply. I didn't contribute any feedback because I thought they had already expressed the need for the feature.
What were the questions you were looking for feedback on? Other applications that seem to manage highlighting of found text are AskSam and ContentSaver. UR is superior to those in its organisational abilities, but since switching to UR I have missed being able to easily enter Boolean text searches and seeing search terms highlighted.
