Email theme problems

Hi,

I'm aware I can change the contents of stock emails but there is no control over the overall theme - the colour scheme is as the Clearbooks default template and it uses the logo file I specified for invoices stretched to fit the full width of the email which doesn't look great. I'd like to be able to change the colour scheme to match my custom invoice scheme and either fix the size of the image or be able to apply a different image to emails.
