The ability to use my own formulas, such as calculating percentiles or quartile ranges; I can also create custom charts using SQL queries (SQLite). Sometimes it's difficult when you don't have an idea what values are being displayed in each column/row - eases visualization! It would be great if we could export our results into other graphical formats like Powerpoint presentations with additional formatting features added-such diagrams / tables etc.. This program does exactly this but not limited just graph generation only.
