Working on TSCO Presentation Server (version 10.7), I found two possible enhancements about column values rendering on summary table dashboards:
1) Custom mapping renderer: enable regular expression mapping.
Example: I want to highlight by using custom colors or labels all the text/number values that match a given regex. At the moment I have to specify all the values separated by comma, but I might not know all the values in advance.
2) Number and Alert renderer: flexible meaning of good and warn thresholds.
Example: I want to render through colored number or alert symbols a column which meaning is "days to deadline". In this case I want to highlight in red all the values below a given threshold (30 days for example) but at the moment the renderer does not work properly if good threshold value is greater than warn threshold value.
