Smart folders - Today - better not to show mails in "Trash" folder.
The "Today" under "Smart folders" is showing emails under "Trash" folder too. This is not a comfortable UE.
Detailed Description
While within "Today", though it is good to see all of today under one screen, showing the mails under "Trash" complicates the job of the user. Either "Trash" mails can be avoided or shown at the bottom with a sub head "Trash".
Context
Better UE.
Possible Implementation
Showing "Trash" mails under a sub head would give better UE. Likewise, the "Today" screen can have several sub heads accordingly.
But avoiding "Trash" folder under "Today" itself is fine.
