Changing to PB 4.x was the badest thing last time.

• Helix ultimate: megamenu with Canvas kills the tablets portrait view with false breakpoints; not useable without more work
• PB4: oversight of pages not showing all pages after "check in" from blocked pages. There are only 20 pages to see. After clicking another menu point and then back to pages overview all pages are shown.
• PB4 startpage "Don't sho this site again" is shown every time new
• PB4: not working correct in Joomla! articles. Things build with PB4 are onliy shown with after using "read more". No main content possible.

The work and usability with PB4 is much worther than older versions. Maybe it's time to change to YooTheme ...
