We've just added some enhancements to Workflows we hope you'll like!  

You can now delete some or all of the data you've collected via your Workflow.
Find out more information here.
Plus in related functionality you can also now do partial exports, choosing a date/time range for the data you want to export - really useful if you have a high traffic Workflow and do some periodic manual batch processing - and some of our customers have really high traffic Workflows!
