It would be great if it was possible to have a report showing all activities (filtered by the time/type drop downs) - I know you can see these in the activities screen but it is not possible to export from there as it is possible to do from the report screen.
It's great that you can build your own reports and sort the fields where you want them, but you can't save that report with a custom name to reuse on a regular basis.
That would help greatly when manually migrating data from this connect service to personal reports.
Also have CSV output of entire activity tables from those custom reports.
