Hi guys,
I just want to let you know that we have just released a new version of the site. We want to thank you for giving us feedback. Although not everything is fixed or included we think it's a nice release to make YM better.
Please see the release notes in the earlier post for more details.
And yes, the new Viewer is now somewhat hidden in a preview button, but we are still working on it. When it's more finished it will get a more prominent role on the site.
Let us know what you think and we always like suggestions to make YM better!
