[dbojan]

Details

Using mouse: When user selects multiple numerical, values in one column, it could be useful to display sum of those values. Maybe add it in the status bar, or in the tool-tip.

Optionally to also display count, and to do that form multiple selected columns as well.

Right now, the best way to get sum is to select cells, and copy them to Excel, and check status bar in Excel.
