People with access to an AEM author should be able to be quick in recognizing a node as “never published”, “published”, “unpublished”, “modified” and/or “locked”. This should be true in each of the view modes, “Card View”, “Column View” and “List View”.
Current/Experienced Behavior:
a) In Column View, there user has no possibility to get a quick view of the published states. The status of a single file can be verified only when clicking it. b) in Card View a user can see the published status but also does not easily detect whether a node is published or unpublished – although the cards can vary in size in case they need to show more meta data. c) In “List View” a user gets the only possibility to get a pretty quick view of the matter, although – as said earlier – the different icons look pretty alike.
Improved/Expected Behavior:
If the three view modes would be enriched with colours a user would immediately see what status a node is in. I would imagine such colours: red = unpublished, green = published, blue = modified, grey = locked, no colour = never published. Please see the attached “paintings” for an idea I had how this could look like.
Environment Details (AEM version/service pack, any other specifics if applicable):
Tried that out on my local installation with AEM 6.5.13 - we're (still) on on-premise environments - but wasn't successful - as you could imagine anyway. Neither manually - even created full-path-overlays as another test - nor by installing your package.
