New interactive editing mode, page data tab, and more

<!channel> There’s a shiny new interactive editing mode! (This is the new iteration of what was called Focus Mode in the past.) This mode can be simpler and faster.

And an improved Page Data Tab now lets you debug and edit your state and other data.

Plus a bunch of other goodies - check out the full release notes!

in “M” mode, when turning on interactions, then exiting “M” mode (back to design mode), elements on canvas are still interactive, I don’t know if this is the intended behavior

So cool!
