It would be a nice option with a solution to allow for global settings. We have the advanced setting string which I use but it's not as user-friendly and there's just one.
Often with solutions (I've created dozens), I'd like to set global values such as background color, background image selection, number of columns, various sizes (say images for gallery), and other things like this. Based on how this is structured I think this is a more difficult request than it sounds, but thought I'd throw it out there.
