I must see if the POP3 protocoll supports those markings.... AFAIK it does not.
Well, I could implement that by adding a local "memory" of wich mails you have read....
What it already does is telling you how many new ones you have
And I am currently puzzling on a pretty simple - but somehow nice and functional - addressbook
[EDIT]
OK, lol, the readmarks are already working

As well as the addressbook

It's a pretty simple one, like said, but does it's job quite well IMO.
I'll now spend some time with editing the templates a bit and then install a second beta on by test board for everyone to look at.
Once the templates look nice and everything seems to work I'll release a public beta for everyone to install and try by themselfs
