I aslso have a 14 MB Windows shell utility that lets me quickly send one or multiple documents to my Kindle device or library. I can access the docs on my Kindle or just toggle the information to remain in my personal Kindle library for safe keeping. This is an important facility because one of my daughters shares my Kindle log-in and she can see draft documents that I'm producing for Kindle and Blurb book distribution.
Save-to-Kindle also adds a virtual printer to Windows so I can click "Print" and then "Send to Kindle" in any application. This means I can automatically generate a PDF and send to my Kindle library any web page or file I'm examining. This has helped improve my work flow.
One interesting side effect I've noticed is that some PDFs of single screens will open on my Kindle but they won't open as PDFs inside Evernote. It's as though Amazon has a better way of handling Acrobat files.
Send to Kindle is exposed by right-clicking an item in Windows and if the content is supported, the tool retains my last page read, bookmarks, notes, annotations, and highlights for view on my Kindle.
Once the saved item is inside my Kindle library, I can see it on all Kindle devices associated with my account and I can download and open the item in whatever access point I'm using. This means I'm getting free Amazon cloud storage space by using a Kindle as one of the touchpoints. I do not encounter any storage limit advisories when saving documents this way.
