The calculation executive summary and calculation detailed summary would be improved by adding a time stamp near the date and file name at the bottom of the reports' pages. It would be helpful to be able to add a note to the reports describing that particular calculation "run" in order to more effectively understand and document how tweaks to the model impact the hydraulic results for the system. Ideally, there would also be a way to add columns to the catchment, link, node, inlet, and pond summary tables to also document what was tweaked in the model (pipe slopes, inlet type, etc.). Flex table exports can be used for this type of documentation with any number of columns, but they don't allow for the inclusion of what is often a critical variable, the rainfall runoff return event (aka design year).
