In the recent 4.01.05 GBC release, there is a new theme, the "compact" theme. Themes allow you to have different look and feels when viewing a Genero application. Previous releases of the GBC have included a "highcontrast" theme to illustrate what can be done with themes in terms of altering colors and sizes to aid accessibility.
The new "compact" theme focuses on sizing and aims to have a 4.x Universal Rendering screen take a similar amount of space as a 3.x Native Genero Desktop Client application. If you feel your UR screens are too big, and perhaps even rendering with scrollbars, have a look at this new theme. I would also encourage you to look behind the scenes at the configuration needed for themes as it might help you in our own customisations.
