I do my whole order of service in a single sermon so that I don't have to switch between sermon documents. Because of that, the word count and time estimate at the bottom of the sermon document includes psalm introductions, Bible readings, and other things. It would be nice if there was a word count and time estimate for the selected text as well as for the whole sermon document. That way I could temporarily select the sermon portion and get a more accurate estimate for the sermon itself.
For example, instead of "6,626 words (55 minutes)", display "6,626 words, 55 minutes" when no text is selected, and "6,626 words, 55 minutes (4638 words, 38.5 words selected)" when text is selected.
