Cell-level comments in Excel are highly valuable. The PowerPane cell comments feature speeds things up by letting you add a new comment simply by selecting the cell and typing into the comments box. No more right-clicking!
And, the "Indicators" option lets you turn the little red triangle
icons on or off at the workbook level. This is particularly helpful
when you have a comment-heavy workbook you'd like to share with
others, but not overwhelm them with the comments.
