When I open I'd workflow, I'd like the option click on "something" to see content previous created for the workflow.  The content I'd use most frequently is:  How was the INPUT data obtained?  ALL of the Alteryx workflows I will be creating with my current employer will require some level of pre-build of the data sources.  I would like to document the pre-build requirements (could be pages of text, so "comments" aren't optimal) and be able to ask for them as needed.

Optimally, this feature would accept .docx, .pdf and other standard formats.  Another option would be to support a URL that would link me to the content.  For my purposes, this would be even more advantageous as all of our knowledge content is on-line.
