TBD - What does 'preview' mean for bulk exports? According to doc: "Fully render the display for the purposes of a live preview or some other AJAXy reason. [views_plugin_display.inc:1877]"

Not sure it makes sense for Bulk exports to be previewed in this manner? We need the user's full attention to run the batch. Suggestions: 1) Provide a link to execute the view? 2) Provide a link to the last file we generated?? 3) Show a table of the first 20 results?
