Ok, that's fair. I understand the "we haven't gotten to it yet" answer, as someone who's had to give it plenty of times.
Just to be clear, I think the big issue for us is the way it tries to make a line for each mapped task. When you have a mapped task with a couple thousand tasks, it kind of balloons out into this massive thing, which gets harder to read the longer the tasks run on. We've been relying on our logs to figure out what's finished and what's failed.
The UI also just kind of crashed when we had about 4,000 tasks, but I'm hoping that's an us problem and not a normal prefect 2 thing.
