My favorite journal - the electronic journal of combinatorics - doesn't have page limits because it never gets printed. You can also use as many colors as you like in your diagrams! Meanwhile, a friend of mine uses a bool in their LaTeX files for 'idiot mode'; flip it on and recompile to get the painfully detailed versions of all the proofs. Since the source is on the arxiv, it means each paper has a kind of half-hidden long version.
