I am designing a my.yahoo style solution. I noticed
that Yahoo's edit pages have a Finished button only
and no Cancel button.
I went to Edit->Edit Content for the Headlines panel.
I clicked on Delete All Headline Choices, but did not
press Finished. Then, I clicked on my Home button,
and all my headlines were gone. Isn't that a design
error?
If you want to try a less destructive interaction, add
some headline sections, but don't click Finished.
Click "Home" button on browser (assuming my.yahoo.com
is your home). The new headlines will appear in your
news headlines.
