What happened:
When there are a lot of events, it's hard to know which is the recent commit.
What you expected to happen:
It makes it easier to see which is the latest commit.
How to reproduce it:
Look for the latest commit in the pipeline with many events in the pipeline.
Let me propose about how work it looks like.

Is it looks good? @jithine @tkyi @adong
Let me suggest another idea. What do you think if we put a green box around the latest commit SHA and show the tag as last successful?
Your suggestion seems reasonable. What we want to express about sha should be decorated on sha.

It would be better to have a couple of target SHA in the image to help us visualize the image, but I think it's good.
Basically, I agree with Proposal 2.
However, we need to think about the color of the latest commit sha.
In screwdriver.cd, green means success.
The color of last successful should be green.
@ibu1224 Thank you. The image below reflects your idea. And I think this is the best.

@yoshwata couple of questions
@jithine Thanks
will events still be sorted chronologically in the events list ?
Yes, I'm not going to care about sorting in this issue.
Since we already have the green check mark against the successful event what more info does the label provide ?
When a pipeline has a lot of failed or skipped build, it provides visibility for users to search latest successful build by their eyes with scrolling up or down.
Is the idea to also leverage success states of the pipelines from #2199 ?
I've concerned but no idea, sorry.
If there are multiple events with last commit sha will all of them get the blue label ?
Yes! In that case all of last commit sha get blue label.
Slightly related to #1820
Thanks for linking. One event group should gets one blue label. I think it is beautiful.

It would be good to highlight the areas in the red frame in the following image.
