Priority list:
1-9 as in vim (9=required for next release, 5=would be nice, 1=probably not)

BUGS:
- multiple windows do not work at all, so :q will close the whole browser session, even when there are other windows which has tabs
- http://en.wikipedia.org/wiki/Portal:Current_events - 'f' shows more hints than 'F' (on left side of nav bar)
- dpb| 09:09:56  dpb :: when I save a page with vimperator, it adds  near the end of it.. kinda annoying
  dpb| 09:11:50  dpb :: and this happens only when saving the complete
     webpage, saving  only the html works just fine..
- add window resize support to hints
- can't reverse tab through the vimperator toolbar
- gu and gU don't work on local files properly
- :noremap does not work fully
- pvh option not working
- searching backwards incrementally does not work i.e. with 'incsearch' set

FEATURES:
9 :command for new commands
9 :sidebar {addons/bookmarks/history/downloads/...} command with tab completion
  (and automatically getting possible sidebar elements from View->sidebar
9 make hints smarter, not only with characters from from hintchars, but use "NE" or "NP" for 'new posts' e.g. (might be too slow)
8 middleclick in content == p, and if command line is open, paste there the clipboard buffer
8 it would be nice to have :(undo|back|forward)  w/ tab completion support
7 [ctrl-o/i] to Go back to a Previous Position (done partly, however currenty does not use a per tab jumplist)
7 whereever possible: get rid of dialogs and ask console-like dialog questions or write error prompts directly on the webpage or with :echo()
7 3d should delete 3 tabs
6 downloading of links to filesystem (:save )
6 autocommands (BrowserStart, BrowserQuit, TabClose, TabOpen, TabChanged, PageLoaded, any more?)
6 vim like mappings for caret mode and textboxes (i to start caret mode?)
  http://nigel.mcnie.name/gnawt/ has a somewhat working implementation
6 pipe selected text/link/website to an external command
6 macros (qq)
6 gf = view source?
6 make a real one-tab-mode, divert _all_ other targets, possible by setting a firefox option (set popup=0-3)
6 page info support (ctrl-g, g)
5 Use arrow keys in preview window, and ctrl-w+j/k to switch to from preview window
5 Sort :open completion by date? (use 'wildsort')
5 make use of the ] and [ keys to e.g. jump to the next heading ]], next image ]i, previous textbox [t and so on
5 add tag and keyword support to adding/deleting bookmarks
4 Support multiple top-level windows?
3 Splitting Windows with [:sp :vsp ctrl-w,s ctrl-w,v] and closing with [ctrl-w,q], moving with [ctrl-w,w or tab]
  have a look into the split browser extension
3 :set should also set about:config options (with autocomplete)
- many other ideas are listed in the wiki

RANDOM IDEAS:
* numbered tabs
* https://addons.mozilla.org/en-US/firefox/addon/4125 - use vim to edit text fields
* Would it be possible to add a setting "maxcompletionsshown" and 
  "maxpreviewwindowheight" or something like this?
* 16:06:04       bartman| maxauthority: feature idea: what if :n and :N searched the 
                        page and if they found a unique href=*next.* or 
                        href=.*prev.* they would follow that link?
* hide scrollbars: http://rafb.net/p/YHRhEe47.html (window.content.document.body.style.overflow = "hidden")
