How about building an export function to a database or Excel (not just .csv).
I love Tableau Prep, however its export options are very limited.
Your competitor products (such as Alteryx) offer many data export options once a data flow is completed.
Please, please, please build such an option - it'll make your product even more awesome and will enable it to be used widely in an enterprise.
