Is there a markdown-mode similar to org-mode?

Is there a markdown-mode similar to org-mode?

I'm using markdown-mode right now to edit .md files and I find myself
missing a lot of functionality I have in org-mode.

This is what I'm missing at first edit, but there is probably more that
I can't think about right now:

 1. TAB to open and close trees (including unordered lists and ordered
    lists)
 2. Treating lists similar to headings
 3. Alt-arrow right and Alt-arrow left to switch level of headings and
    list items, and correctly change numbering of ordered lists (C-c
    arrow left and C-c arrow right does part of the work, but not the
    fixing of numbers in ordered lists. Also C-c arrow is a bit more
    clumsy than Alt-arrow but that can be fixed by a custom key
    binding))
    So: changing of numbering in ordered list is what is missing here
 4. Correctly set numbering of ordered lists when using Alt-RET to
    create a new list item
 5. C-, to create a correctly indented code block and C-' to edit the
    content of the code block in a separate buffer

Anyone know of a markown-mode with the above functionality?

Ie. opening and closing of trees (both headings and lists), fixing of
ordered list numbering and editing of code blocks?

First workaround I thought of was to do the edit in org-mode and just
export to markdown, but I have to cooperate with other people who will
edit the .md file and have no idea of what to do with the .org file, so
that's out.

Thanks!
