Hi Christian, We will discuss in the team your request about the 32K limit in the widgets. But I have a remark at this point. I believe that a good table widget should be dynamic and not reserve the space in a large physical widget that you have to scroll anyhow to visualize it on any today screen. Otherwise you will have memory problems and a very bad performance. We know that we should provide a good matrix widget for scanning Trees and operations a la Excel. I hope that we will be able to implement such a widget in the coming months.
