Thanks for these suggestions.
1. There should be a Progress Bar or a message displayed when performing an Automatch
Definitely. I agree!
2. 'Use Regular Expression' should be clicked by default in Munge Process definitions.
I do use regular expressions most of the time, but I was afraid that the users of the "Classic MatchMaker" would get tripped up by this if it was on by default. I'll have a chat with some of them and see what they think.
