Review for Color Folders by phubert
Rated 2 out of 5 stars
Later versions of Thunderbird have been wiping-out all color assignments. I have gone through and re-colored my folders over a half dozen times so far and with perhaps 200 folders this isn't trivial.
I donated once and am willing to donate again - I realize it isn't nearly enough to pay for development time - I'm not rich! But I can hope this problem will be resolved.
