It would be nice to be able to relabel the column headers. This becomes even more important as you start getting 4 or 5 metrics and the names don't fit. Also, we, like many others, label our events/variables with (vXX, cXX or eXX) which is kind of clunky if you want to share the report with somebody.
Also, the Community link in the Help menu lists as 'undefined' when you are in the tool.
