A simple attempt at making the page responsive by detaching it from the margins, centering, and making it resize to fit the browser with fluidity (% of the browser width).
Little blue edit-button, nice and clear call to action for modifying the bug-report.
Dedicated thumbnails column looks good when there is a lot of text content. Highlighted headline? A little much.
I LOVE this byline technique: a history of the bug-report’s state-changes inlined with color-coding, symmetry, and good horizontal rhythm. You can see who wrote the bug-report, and how it’s progressing in one style and one place. Having it in one repeating style also helps make it disappear into the background while reading.
Negative-space comments? Ew 
I like the layout below and it’s visual style. But it still doesn’t have that pop high-design startup site look.
