There has not been a Web Modeler release with this UI update (but the PR is merged in so that's good!), so I've been hanging on to it. I can always backport if need be. @akeller

Update that this has not yet been updated in the UI, but once a release goes out with https://github.com/camunda/marketplace-api/pull/91 it should be.
