Often I find myself in a situation where I would like to add some information for the “future me”. A few lines documentation about a node or the workflow, so I can for example later remember why I made certain choices, or what the purpose is of certain actions (also useful to avoid really long describing node titles).
The iOS Shortcuts app has a nice feature for this. You can add a “Comment” action to a workflow. A comment “action” does nothing when executing a shortcut. Its only purpose is to add explanatory text in between actions.
So, my feature request would be: a Comment node, inspired by iOS Shortcuts comments, that can be used to add comments to the workflow, but does nothing in terms of input/output.
