The previous (existing) system likely provided too many page options, some of such were used regularly but designed for only occasionally use. We've removed the 'noise' from the standard panel and hidden certain features in a an 'advanced' tab.
The single page creation tab will now be used for all one-click pages, such as the standard entry pages, redirect pages, and nested pages, but we've also added a facility for fact find and other reports.
The update was necessary to support the new Solis module which will often create over 15 automated pages as part of a standard campaign.
We'll send an email tomorrow providing an update but you can expect the new system to be live on Tuesday.
