Apple Mail and Archive 'folders'
So here is the question:
I have been using Thunderbird as my email client for some time, with good success. But with the release of Lion, and some of the new features in Apple Mail, I decided to try the Apple email client again, and I like it quite well.
But one feature that I used in Thunderbird was the ability to create 'saved folders' to save previously read email. So I could have a folder named 'reciepts' or 'medical' or 'bills', etc. to quickly be able to find a saved email by category.
So while I do love the new Apple Mail, I cannot figure out how to duplicate this feature. Apple Mail does not seem to have the ability that I can find to duplicate this functionality, which I think is critical. It does have the 'Archive' feature, which is nice, but I need to be able to create sub-folders within the Archive folder.
Can someone offer insite into options to add this functionality, unless I am missing something?
Thanks!
