TigerDesigner is the tool used to design a version. What you can do in it differs based on the type of version you have created.
Use page layouts or a layout library template containing pre-configured interactivity. Add content into fixed panels and control the appearance using theme/branding. Although restricting some control, layout libraries help to create a consistent, professional looking design. It may be tempting to create a design from scratch, but once you are familiar with it, the layout library can make designing an version a lot less time-consuming.
Editable Templates/Blank Design
Have full control of your design and add and manipulate individual panels. Different panel types, settings and palettes are available.
A design that includes pre-configured interactivity. The panels and interactivity can be edited, added and removed.
A completely blank canvas. Add panels to your design and add interactivity.
Editable templates or blank design are not recommended unless you have advanced design skills.
