In the web client, when a grid is present in the user step, an option appears to expand the UI to the full browser window.

Feature request: always show the expand option for the user's step (regardless of whether there is a grid inside).

Also, make it a designer option to default to expanded or collapsed. Today it seems to remember my choice next time I run the app, but that is probably only for that app and that browser. Be able to control it more generally, both as an admin and as a user.
