Introduction
The release of Layout Developer 12.1.0.0 provides some enhancements to the user interface. In this document, they will be described in two parts:
Yellow Bar Updates — changes to the behaviour of the yellow bar intended to make life easier for users
Print Dialog Update — a minor change to the print dialog to make it easier to set cutting guides when printing
The major interface changes — JavaScript toolbars and the Insert Markup feature — will be described in their own separate chapters as these are significantly larger features.
