Bright, clear and customisable Rated 5 out of 5 stars

brilliant and clear! any chance of an update to make it compatible with the current version of Thunderbird?
It is so easy to give each account a different colour, help reduces confusion if you run several email accounts, and most of all in doing this it is very easily customised.
You can customise the colours to appear in each window or view separately and the fonts as well. Being able to choose exact shades make it easy to configure to your own taste. Since I've been using it, my time spent looking for emails and checking accounts has been reduced. I would recommend this to anyone. it does not interfere with the stablility of thunderbird in any way.

This review is for a previous version of the add-on (3.2).
