I need to know how to do the following in Mail (Thunderbird does this but I need to use Mail):
How do I color-code email in the inbox with different colors representing user-determined categories such as IMPORTANT, OFFICE, PERSONAL for example, so that I can then search by color to easily find mail in these categories?
Mail will let me flag important emails but the flags are too little to stand out and be easily seen. There are also no categories assigned to each color. I want to be able to look at my inbox, quickly search by color to find mail identified earlier as PERSONAL, for instance, so that I can then reply.
