Two general observations from trying it out:

• The text all being blue makes everything look like a link. Especially if / when we remove the underlines from links, that's going to be very confusing. I'd say make the non-link text black.
• The status badges are definitely harder to notice at a glance than in the old UI. The old way had the a nice strong color for the badge, with white text. The new way has a super light color for the badge and then it's really only the text that has the stronger color. It just feels way easier to miss at a glance that something is in "stopped" status.

That older style one stands out a lot more to me.

Some observations from testing:

• There is no confirmation dialog when deleting a system.
• The buttons for the system feel like they should be right aligned with the buttons for the instances (as they were in the old UI).
• There is no feedback or response when you stop a system or instance. The status does not change from RUNNING to STOPPED (or vice versa). You have to reload the page to see the update. The websocket connection does not appear to be working correctly so that is possible an unrelated issue that needs to be addressed.
