A typical annoyance with Excel is that you are in Sheet 11, and when
you make a change to a cell, you want to see how that impacts
another cell located in another worksheet. Toggling between
worksheets, or scrolling to locate that impacted cell can be a major
inconvenience. PowerPane for Excel lets you designate certain
cells as "Watch Cells" that you will be able to monitor no matter
where you are in your workbook. Changes made to a related cell
will automatically be shown in your Watch Cell panel. And,
click on the value of the Watch Cell and you'll be immediately taken
to the related cell you are monitoring.
