A 'Conversion Variables' screen that actually doesn't freeze everytime you change something

Simply put, the Report Suites > Conversion > Conversion Variables screen freezes everytime I try to open and close evars, and upon loading the page it freezes briefly, so that it can take up to 2 or 3 minutes just to change an evar. It would be nice if this screen got a redesign so it would work much more quickly.
