  The Grid and Cloud User Support Environment (gUSE) enables users convenient
and easy access to grid and cloud infrastructures by providing a general
purpose, workflow-oriented graphical user interface to create and run workflows
on various Distributed Computing Infrastructures (DCIs). Its arrangements for
creating and modifying existing workflows are, however, non-intuitive and
cumbersome due to the technologies and architecture employed by gUSE. In this
paper, we outline the first integrated web-based workflow editor for gUSE with
the aim of improving the user experience for those with industrial data
workflows and the wider gUSE community. We report initial assessments of the
editor's utility based on users' feedback. We argue that combining access to
diverse scalable resources with improved workflow creation tools is important
for all big data applications and research infrastructures.
