Would like to see a color palette. This is enabled in SnagIt 13 (although I had to experiment with it before I could see how it works), but I do not see it in Camtasia 9.
I often work with a color library in my other creative tools (e.g. Creative Cloud, Articulate Storyline and Lectora Inspire) to keep our company presentations consistent. In the meantime, I can store the colors in the Library.
