The icon on that indicates it is a saved search.

Ctrl+Shift+F to get to the search (or use the menu) Then you would search for age in days as being less than 1 Finally save as search folder using the button at the bottom.

Note that when you save the search it will appear where you save it. So if you select the account it will appear in the top level folders for the account. If you select the inbox for the account (flyout in the location) then it will appear in the inbox.

You might also want to look at using group by sort by in your inbox as you appear to be largely implementing this inbox sort in a group of folders under the inbox.

When I set the menu entry to the following

My inbox layout changes to the image shown below. Where I have expanded the "Today" entry to show today's emails. I understand this is similar to something outlook does in displaying sorted mail under list of when it was dated.

Matt, I was able to follow your directions, I think ok. I now have a new folder under Today folder. I was trying to move Today above Yesterday. No can do. Looked at Gmail too. No folder. Any more ideas? I'll keep trying....... Thanks.

Boy I screwed up the program!

Matt, Renamed folder originally moved. Recreated Today folder. Copied files from Silly folder to Inbox. Did Alt+T+R. All good now. Thanks again.
