I don't personally take advantage of Celigo's offer to use existing steps when adding a lookup to a flow, but maybe others do?
I would like a way to turn this feature off, this could be a user profile preference?
Other than being distracting and unwanted, here's a real, evidence based reason:
Each keystroke triggers a request to the mother ship for suggestions, each one! LOL
For me to create that simple lookup and type a description generated 168 HTTP requests to Celigo and somewhere around 5MB of network traffic. It also slows down my browser so my typing has latency, you know ... l...a....t....e....n....c...y
Sure, subsequent keystrokes seem to cancel the previous pending request, but at what stage? How much bandwidth is already being used? I'd think Celigo's AWS bill may be impacted as well 
Please give us an option to turn this off. Don't want the feature, it doesn't help me, it wastes resources and creates a degraded user experience.
