I kinda agree with this, especially since it already members the last you've used (so most people won't notice it in their daily use).

This will also somewhat resolve the issue that users with big setups have reported where loading the "States" tab takes a long time. If they go to the tab by design, the load time of course stays the same, but by setting "YAML" as the new initial tab, that gets circumvented for all users that just want o check the config and never actually go to "States".

Plus what Frank said lessens the impact for everyone else that actually needs the "States" tab often (aka devs like me that like to test UI behavior by manually manipulating states 😆).

I don't have a strong opinion on this, except I've seen some people ask for it. When we move YAML to the first tab, other people will probably ask to undo this change. So I think we have to choose what makes the most sense.
