The most common comment we received about PrimalPad was about the choice of color for the skin. Many users emailed us, expressing that they would wish for a different choice than the carbon theme.
Since PrimalPad is a statically linked no-install executable, there is no on the fly switching as in PrimalScript or many other SAPIEN tools.
Stuck in a hotel room one night at TechEd I had plenty of time to re-link PrimalPad with all the skins we have available.
So now you have a choice of Carbon, Luna, Aqua, Silver and Obsidian skins in 32 and 64 bit flavors.
