Started playing with 0.36 too. Trmpetto’s post above was really helpful! I too did not find the dark mode and the choice of editor type at first.
Experienced the same as Trumpetto’s point 3.
The block editor takes some getting used to… So far it tends to distract from pure writing. ( I had a joke in my head about the block editor and writer’s block. I won’t tell it here 😉 We’ll see how it goes after getting more used to it.
