Good job. Perfect fit for a programmer with slight designer tendencies :)

Found a new theme to use, changed a few colors and got a result I was happy with.

However, probably not your fault, after changing one background color, and resetting it to opaque, the theme is no longer valid. Any idea how I can get a more descriptive error message besides: Error loading colour scheme Packages/Color Scheme - Default/Notebook.tmtheme: Unrecognised plist element key
