Messy? Isn't one of the points of having multiple accounts to reduce mess?

Yeah except having to navigate between the two can be tricky. Also that means we have multiple dynamos and multiple cognitos (in our case, test and prod), which is a pain.

I use Firefox for the prod console and Chrome for the test console. Obviously that system doesn't scale past 3-4 accounts. ;)

Firefox Container Tabs work well here for quite a while. But after 20 or so the list of containers will get very long.

I would say that once you get beyond those additional two-three accounts, you have tackled the mess and scaling to 1500 gets easier. And yes it's mind blowing.
