How can I enable steps logging within Photoshop that I can save to a file?

I'm using the latest Photoshop 2015 version with Windows 10.

I’m getting better at making jpgs from RAW files, but am not always 100% satisfied with the results, so I always save the RAW files that I can go back to at a later date when my Photoshop skills have gotten better.  I of course, save the associated XMP files so I can see what edits I made with Adobe Camera Raw, however, once I start making changes to the NRW in Photoshop after I hit “open” within Adobe Camera RAW, unless I manually keep a spreadsheet or some other document of the changes I make, I’ll later have no idea what I did. 

For example, I may select the subject and then increase the brightness by 31%, the contrast by 62%, and then increase the saturation by 12%, then select the inverse and decrease the brightness by 24% before saving the jpg.  So, if I later want to see if I can make a better jpg from the file, I’d like to have the changes logged somewhere that I can use as a reference.  I’m well aware that I can save the PSD file so I can start where I had off, but this is not what I’m looking for. I just tried an exercise like the above and opened the history panel.  It had a section for brightness/contrast, but didn’t bother to show how much I changed the brightness and contrast, and was there any way to export the history.

It would be a major pain to have to take the time to manually document all the Photoshop steps I take, and a screen recorder isn’t a practical solution.  I can’t be the only person who wants this logging.  Is there any way to accomplish this natively from within Photoshop, or perhaps with some third-party utility?  To be clear, I want to export the detailed steps to an easy to read file.
