What challenge are you facing?

When a concourse installation contains dozens of pipelines, and some of them may be paused for a long time, it is difficult for the whole team to remember why exactly is it paused.
It would be nice to have annotations visible on the pipeline, so that the necessary context (reason for pipeline being paused, known reasons for failures, etc...) can be shared across the team

A Modest Proposal

Introduce an annotation field in the pipeline configuration. When present, the text in the annotation can be displayed as a sticky in the top left corner of the pipeline. Markdown formatting
for the text would be a nice to have.
