Proposed Feature

Displaying the commit/image/chart version for each stage that are present on the Project's page would show engineers what has been deployed.

Motivation

This would provide "at-a-glance" visibility to members on what has been deployed from the Projects page, without the need to drill deeper into the project itself.

Example: A QA engineer wants to view what version has gone out into the test environment. They already have access to Kargo to view deployments, they can simply see the version from the project page.

Suggested Implementation

I was able to hack something together into ui/src/features/common/stage-tag.tsx that displayed the promotion status into the stage. I don't think this is as scalable as I would like it to be, hence "hack". I am limited by my experience with React.

Example

I'm not sure how we'd make this look nice for Stages that have multiple Freight (from different Warehouses) or even those that have a single piece of Freight, but that Freight references multiple artifacts.

I think we could potentially do it for Stages/Freight where there's precisely one artifact.

@Marvin9 wdyt?

This is a good point, what about moving the versions down to the tooltip that is provided on-hover, example:

The list of freights are already provided there, so attaching additional information seems simple enough.

I am afraid when there are more stages how it will look, eventually we have to hide some things anyways. Me and @rpelczar are thinking to have summary view instead of individual details. For example x stages, y failed. What do you think about this?

[krancour]

@Marvin9 I believe I agree with the idea of a summary here. imho, the issue with the project list page isn't too little information, it's too much. I know this is almost exactly the opposite of what @mimartin12 is requesting. We don't need to rush this decision. Maybe @jessesuen has an opinion as well.
