Just an FYI guys - Work on the new version has continued; however, it appears that Gauss and PPC's may have their mechanics changed in an upcoming patch according to Paul's Command Chair post. I wont be committing any more time to this until I can verify all the changes.
i was just about to post this here, either way, the overlay will be quite different if not pretty useless
Just came across this lovely thread, and I don't think the overlay was rendered useless. On the other hand, setting the gauss into groups 4, 5, and 6 does a handy job of giving a bigger "charge time" visualization without much effort.
