I shared it with my team too and everyone is greatly appreciating the changes!

Some feedback from some debugging just now: We were trying to figure out why a flow run’s state changed to crashed, and then to completed, 8 hours later. On the flow run page, it would be helpful to a. see state transitions, and b. state details (e.g. the message and timestamp). For now, I wrote some quick Python to get the data:

#+begin_src python :dir .. :python "uv run python" :results output
import asyncio
from uuid import UUID
from prefect.client.orchestration import get_client

async def main():
    client = get_client()
    flow_run_id = UUID("068ee452-a5a9-7017-8000-0a8be9e28f45")
    flow_run_states = await client.read_flow_run_states(flow_run_id)
    for flow_run_state in flow_run_states:
        print(flow_run_state, flow_run_state.timestamp, flow_run_state.data, flow_run_state.state_details)

asyncio.run(main())
#+end_src

Just coming in again to say that I’ve noticed a ton of other smaller things too, like the workspace/profile dropdown, that are all very nice!

I would give you a fiver though for auto-theme switching to match my system preference 😉

I actually looked at the Prefect code to see if I could create a PR for it, but ran out of time, haha

The new settings page seems snappier too, from what I remember

I did do my part in https://github.com/PrefectHQ/prefect/pull/19240 though 😆
