I noticed a few days ago, when I logged into GoToWebinar, the old webinar layout (ie old software) came up, not the new one with the "tiles" layout.
I personally find the old layout more functional - some people may find the "tiles" layout prettier, I personally don't, but that's a matter of taste.
I would be happier if the company would use their software resources to
a. Fix any bugs in the existing software, and
b. Add features to the existing software
rather than spend the effort to reinvent the wheel.
