The new Theme Manager is now taking shape and I have been able to generate some sample layouts.
There are a number of changes being introduced in the new versions. The most significant is that themes will need to be exported from version 1 and imported into version 2 due to internal changes in the storage mechanism. The import will correct the structure and add defaults where appropriate.
Other changes include:
Real Font sizes not percentages on the screen.
Ability to set the font size and color for footers
Background rendering for circles.
Two examples are below.
