I have gone through sights. You are on the road to making a good 'dashboard' tool, but clearly not there yet for the application i need.
I would suggest adding more widgets and better display of data and various infographics. For example, if i am going to drop a table of "per cent complete" for the project on various tasks, that should be straight forward, it is not as the tasks are not associated and i have to add another table.
If i was to show per forma graphic as to progress vs planned on time and cost and resources (ie pie, line, bar graph) then i need a graphic that will allow that. There is none.
From the looks of it I think smartsheets is still stuck in the same construct of tables and trying to re-adapt the smartsheet core engine. You may need to depart from that with more widgets or something.
When you get there and want to give a demo in a few months you are free to contact me but for now i will keep exporting to excel.
