I read with interest this post:

I am looking for this exact function: The ability to export select entries through the Bulk Action drop down list on the Entries page. I was preparing to try to hire someone to create a plugin to do this.
You said this is in the works. Any idea how soon that function will be available? Also, would you consider adding a button within the entry detail to export just that record?
