Review for Nostalgy by Realraven (Axel Grude)
Rated 5 out of 5 stars
Now this IS really useful, just installed it and my several Inbox and Sent folders look a lot more manageable. If you're an email magpie and keep everything like me, but in a folder structure, this is indispensable. Very good addition to Quickfolders!
