I'm testing Zimbra and unless some curve ball hits me when I'm not looking, I expect to launch this by the end of the trial.
A feature that I would love to see added, is the ability to right-click on any email address in a message and select an option "Copy Email Address". Gmail has this and I find it very useful in daily operations.
When viewing a message, there tends to be some black space to the right of the email addresses and subject. This seems like an ideal spot to put a few tool icons or message information... something...
Shortcuts... I'm trying to use the m+r to mark messages as read... nothing seems to happen at least in FireFox. I'll search for clues after in case this is known.
English USA/UK/AU is ok, but what about English CA? We spell some things differently up here...
