I also have similar issues with the text processing.
I like the model they use that everything is a block - you get predictable behaviour, but I do think the normal shortcut for select all should select a page, and that I should be able to select text from multiple paragraphs using keyboard commands (if you do ctrl+shift+arrow you get stuck at the edge of a block).
