Just as a warning to those, who didn´t read the release notes for yesterday´s update to 13v4.
9 out of 12 design families are deprecated and will probably fade away with the release of FM 14.
Most important is, that the classic design theme is deprecated too - this will mean a lot of work for many of us.
Plus changing the design to the remaining themes just isn´t a one click operation either - so beware.
I think it´s quite astonishing, that this really huge change in the future is buried in an updater release note.
