I’m just starting to utilize Arrange Mode and find it very useful. One thing that would help me a lot however is if there were an additional selection mode of Markdown Section. For example, being able to move L1 Headers around, or L2 Headers around and catch all of the paragraphs within them. From what I can see is that’s not possible today, but I could easily be missing something.
That is not currently possible, no. Would be a nice addition.
