"...a message can be in more than one folder if it pertains to two different subjects" That's not a benefit. It complicates things. Folders are simpler - one location, one parent, one place to go and find it. Average users can understand folders. Heck, expert users can use folders immediately without having to figure anything else out. If nested tags are better than straight hierarchies for storing and finding things...where are all of the nested tag file systems? In a nested tag file system - would I have to go all the way to a settings dialog to create a new label like in Gmail? Also, look at this guy's post about how "Gmail sucks when you have lots of mail" - and his response to someone recommending nested tags (Apparently, you can't just drag an email to nested tag.) - https://plus.google.com/105059362788808645801/posts/3amd9ZMiq3k https://plus.google.com/105059362788808645801/posts/3amd9ZMi... All the web-app loving hipsters jump on his case for not "knowing the tool". I love it. How about just give us a tool that works like we expect? Who wants to invest time figuring out a new email client that has very questionable benefits?
