Rated 4 out of 5 stars

Extremely useful and easy to use.

As others have noted, the renaming dialogue produces a spinner, then an "X" and seems to have failed. But, it hasn't actually failed. The renamed mail finally appears right next to the original version, which I then delete.

Unfortunately the above spinner+X process happens at every renaming, and takes between 10-15 seconds, during which nothing else can be done. A significant upgrade would reduce the wait to a second or two.

Thanks for a nice add-on and for listening.
