First of all I want to thank you for choosing Telerik Controls and particularly RadPivotGrid. We are really happy to receive feedback from our customers and we really appreciate your suggestions. Let me clarify some of them:
1) We cover most of the measures you have asked for, but we'll consider adding the missing ones.
2) Could you give more information what do you mean? We have plans to implement PivotCharts, but I'm not able to give you exact date when it will be ready.
3) Not sure about this - could you give an example or such hierarchical pivot grid.
4) Supoprting drilldown is on our to-do list and will be implemented in the future.
5) Coloring of the cells is also in our development plans, most probably it'll be ready for the official release (Q1 2013).
Once again thank you for evaluating RadPivotGrid. Don't hesitate to contact us if you have any more suggestions or concerns.
