When FME prompts for search envelopes or bounding boxes in general, it would be really nice if there were an option to draw the bounding box on a map instead of keying it in one coordinate at a time.
The background map setting from the Data Inspector could be used to provide the context.
Ideally the same option would be available when FME Server prompted for a similar thing as well.

The FME Lizard wants to know -- how useful would this be for you?
