Given a re-write though, I think the way it's moved forward is a bit of a train wreck:
* It's incomplete information wise.
* They threw the baby out with the bathwater as far as UX. Nice things like when you visit a job with failed tests it high-lights that fact and failures; gone.
* They implemented the new log viewer with a virtual scroller. Browser search can search into it, and it has no integrated search. You can select past the buffer size of course. Zero extra value to the user here.
* It seems like the people working on the project have little product empathy. I would almost think it's been outsourced. When very obvious missing feature or issues(compared to the current UI) are pointed out, we get platitudes like "Thanks for letting us know as we iterate on this. We are all in this together!".
* Supposedly it's now being forced on the user base Q1 2020 in this state.
* As a nit, it's uninspired and ugly as sin IMHO from a design standpoint. It looks like an off-the-shelf Atlassian SPA theme. And janky. Somehow the sidebar got wider AND dropped the test explaining the icons?!
The whole thing seems like a boondoggle of epic proportions. Did I mention they seem to also be simultaneously rolling out GraphQL; because GraphQL?! I'm somewhat surprised and saddened there aren't more people pushing back on it and leaving feedback in their forums. Meanwhile we can't filter entire workflows, and we can't filter for PRs. Sigh.
I do like many aspects of their service, so it's a shame to see something play out like this :/
