1 - Automatic Folders:
I think the Folders feature is good, but it can be enhanced with one important upgrade.
All incoming and outgoing emails (Sent) should be allowed to be sorted into a Folder - to an automatically suggested Folder or manual menu selected Folder. Automatically suggested Folders would be based on the history of the senders' past placement in Folders.
I use the menu to sort incoming emails, but it is a hassle to go back to Sent emails to sort to a Folder after sending.
2 - Sub Folders:
We need sub-folders. That is Folders within Folders.
Can these features be added?
