The ability to create and design user friendly multi page reports that are both user friendly and render quickly. Something that would look very similar to what can be done in excel with colored headers and formatted text. The reports could be dynamic based on a series of feature classes or tables and could include maps, charts and tables. Currently the reporting solution is very limiting and the work around of creating layouts with dynamic text is tedious and not ideal. A good reporting solution would also allow for reports to be exported in a variety of formats (PDF, Excel etc.). Online reporting and dashboards are great but having dynamic reports available in the desktop environment is essential, as well. Especially when designing custom push button geoprocessing tools that require reporting as the final output.
