Looks fine to me. I'm interested in @gemorris opinion on proportional width changes

This looks good, a few notes but nothing critical.

1. the ... truncation pattern does not seem to be applying to sub-items like the "hellobedrock2019-hellobedrock.acme.frontend:master-20200524.1" Not sure if this was an oversight or intentional. I'd like to be consistent if possible with our truncation.
2. the fact that the row highlights when I hover, and that we don't have distinct styles for clickable items (only distinct hover styles) is definitely creating some interaction-uncertainty in my mind. The hover state on the row is something I'd like to talk about, as it usually indicates that clicking the row will do something / navigate somewhere. Maybe we don't need it? We do need a more clear style for clickable items but I don't have an answer for that right now, will make a note to try some options though.

All that said I think it is shippable as-is, but would like to try removing the row hover if it is quick, just to remove one potential source of confusion from the UI.

@gemorris Just fixed the truncation pattern on the sub-items. As for the row hover, I'll make a separate issue and PR that in a future update, as I haven't found a fix for this one just yet.
