Hey @backspace

I took a very quick look at this, I'm circle back tomorrow if nobody else has been here. I think my only thing from a user perspective would be..

What's your thoughts on putting the 'most important' thing at the front of the title, so the name of the job or whatever. Tabs are generally pretty small and when they get smaller, if I was to have multiple tabs open I would be able to distinguish between them easier if the name of the job was at the start instead of the word 'Job'

Overall, this seems fine to me other than that, lemme know what you think on ^. Otherwise I'll circle back in the morning and give it a final look over.

Just noticed a little inconsistency between single and double quotes other than that LGTM!

I'm obviously late to the party, but I wanted to look at this too, and it looks nice! And of course there's an ember addon for title management ✨
