Make it easy to see what route the job will take

[yuichi10]

What happened:

When I use complex workflow pipelines, it is difficult to see what route a job has taken.

What you expected to happen:

I want to make it easier to understand the routes associated with a job.
For example, when I click on the job, the edge associated with the job changes color.

How to reproduce it:

Create a complex pipeline. Especially a job has many edges.
