Another thing that I would find useful would be to check if particular row or column, or both exist. It seams that atm we can only check if data within an already created row/column exists. I might be wrong though.
Also sorting rows or columns in alphabetical order by specific row/column of that table. So for example if i have Col "name" i would like to sort all raw but their name alphabetically. And if I have Col "Qty" I would like to sort out by numbers. Both from A-Z/1-xxxx and in reverse from Z-A/xxxxx-1. If those two would be possible to do that would be awesome :)
EDIT: And one last suggestion. Do you think you could make created pages to appear listed in "objects with expressions" window in same fashin as variables when system is selected? That would make the whole process much simpler.
