email STAR colours
May I suggest you to create different colours when putting a 'star' symbol to highlight a message.
Diverse 'star' colours would help me to organise better my emails eg: blue star for documents, red star for urgencies, yellow star for important friends message etc.
The idea is that the user would create his/her own colour code in his/her mind, and the tool would become much more useful.
