One of my designers pointed out this great tip the other day. I usually send PDF files to printers, but occasionally I have to package a job to give to another designer, send to a vendor or archive on a server.
In InDesign CC 2014, you create a package the same way you always have – "File > Package..." but there is an additional twist. When you go to save your packaged folder, two new options are at the bottom of the save dialog box: "Include IDML" and "Include PDF(Print)."
These are definite time savers. I often have to save an IDML file for those who haven't upgraded to Creative Cloud and the ability to save a PDF with a specific preset saves another step.
It's a nice addition by Adobe to make a commonly used feature more powerful.
