Show [Selection Length] of selected audio

At the bottom of the Audacity screen, it shows the [Audio Position], and then the [Start and End of Selection].

Enhancement: Display in an added box, the [Selection Length].

Sometimes I mark the start and end of a selection of audio, and I want to know just how long that selection is; but trying to work it out from the numbers is just Hard Work!
It should be Quick and Easy to implement.

Many thanks.
