I agree. I use Editorial to make quite large outlines. To navigate and work easily with long texts, I want sections to be folded when I open a file.
Several times I by accident I tapped the triangle button in the left corner and the next time I opened that document, everything was unfolded. So I had to fold all these many items manually.
So my wishlist:an undo button for "unfold everything" a button to fold everything put the triangle button in another place
