Sometime ago on another group someone mentioned a feature of 'outlook
express' that highlighted unread threads in a different colour as well
as being embolded. Thunderbird just has them in bold.

I had a look at this back then and found / edited this mod. Lately on
reinstalling things I've realised how visually useful it was for me so
I'll share.


First find your profile folder.

http://kb.mozillazine.org/Profile_folder_-_Thunderbird.

Create (if you don't already have one) a 'chrome' subfolder.

Copy the following lines as a new file in this folder, named
'userChrome.css'.

---------- copy lines below here ----------
@namespace
url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#threadTree treechildren::-moz-tree-cell-text(unread) {
color: DarkBlue !important;
}
#threadTree treechildren::-moz-tree-cell-text(container, closed,
hasUnread, read) {
color: DarkBlue !important;
}
---------- copy lines before here ----------

Restart Thunderbird, and you should find unreads are now coloured.

e&oe!
