Amazon byteflow: Conkeror wishlist

What will be good to see in conkeror:

Session save
Possibility to divide frame into windows
f must complete for form's labels (or input names?)
Closed buffers history (possibility to restore buffer with it history)
Shift-cursors for navigating (walking?) through URLs (Opera's spatial navigation)
Middle button click must open URL in new buffer (this can be done relatively easy with bind to middle-click action)
Select text from keyboard (now possible by C-q F7, but emacs-like shortcuts does not work)

Already exist:

C-k must copy killed text to kill-ring
Possibility to use current page shortcuts (like greader/gmail j/k/r/etc) (C-q sends next key to page, M-C-q sends all keys until Esc)
Tabs (M-x tab-bar-mode or tab_bar_mode(true); in .conkerorrc)
URL history (url_completion_use_history = true; in .conkerorrc)
Save previous active buffer (to have possibility for swapping buffers, for opening it on current buffer close)

Open link in background, add this to .conkerorrc:


interactive("follow-new-buffer-background", 
        "follow to a link in new buffer, opened in background",
        function (I) {
            var target = OPEN_NEW_BUFFER_BACKGROUND;
            var element = yield I.read_browser_object("follow", "Follow", "links", target);
            browser_element_follow(I.buffer, target, element);
        });
define_key(content_buffer_normal_keymap, "M-f", "follow-new-buffer-background");
