Hi brrmek,
thank you for your suggestion. We also believe that it would be a very usefull feature to have more than one unit per unit type. Assuming the the units allready available in e!Sankey diagrams will become 'basic units' the user should be able to enter related units and a coefficient - e.g. if kg is your basic unit, you may enter t for tons and 1000 as coefficient to transform kg to tons. So it is possible to configure each entry, what unit will be used.
... But i can not say anything about the time, this feature will be implemented.
