Function editor in the properties explorer
Place the function editor for defining variables in spreadsheets directly in the properties explorer instead of opening a dedicated window for this purpose. All items from the "Generate data" entry could be placed there for a quick and easy edition and data generation.
This would enable not only quick and easy edition of variables but also an instant visual monitoring of the changes (e.g. modify the mean and observe how a histogram changes).
