This is the Subforum Bulb plugin 0.6 public beta.
Released 2009-01-09 by Andreas Klauer <Andreas.Klauer@metamorpher.de>

 INSTALLATION INSTRUCTIONS

   This plugin is intended for MyBB 1.4.3 / 1.4.4.
   For other versions, see if the changes below apply and
   update the "compatibility" entry in subforum_bulb_info().

   For the plugin to work, you have to change some of the MyBB code.
   Without the changes listed below, the plugin simply won't do anything.

   Do not forget to undo the changes when uninstalling the plugin.

 FILE MODIFICATIONS

   In index.php, find this line:

       $forum_list = build_forumbits();

   Replace it with:

       $forum_list = (function_exists("subforum_bulb_build_forumbits")
                     ? subforum_bulb_build_forumbits()
                     : build_forumbits());

   In forumdisplay.php, find this line:

       $child_forums = build_forumbits($fid, 2);

   Replace it with:

       $child_forums = (function_exists("subforum_bulb_build_forumbits")
                       ? subforum_bulb_build_forumbits($fid, 2)
                       : build_forumbits($fid, 2));

 SETTINGS

   The behaviour of this plugin can be customized via settings.

   This plugin will automatically create a settings group 'Subforum Bulb'
   for you when you activate it. It will NOT, however, remove the group
   when you deactivate / deinstall the plugin. This way you can keep your
   settings, should you choose to activate the plugin again at a later time.

   Available settings:

     Classic Bulbs: (Default: YES)

       When set to YES, Subforum Bulb will stick to the original icons.
       In this mode all the plugin does is prevent a parent forum to be
       marked as unread when there are actually no new posts (MyBB bugfix).

       When set to NO, it will make use of new combined icons that show
       the status of the parent forum and the dominant subforum.

     Mini Subforum Sorting: (Default: NO)

       When set to NO, do nothing.

       When set to YES, it will change the order of the subforums in the
       mini subforum list (subforum 1, subforum 2, and 3 more) so that it
       will show more important subforums first (unread > read > locked).

   If you want to uninstall the plugin for good, you can remove the
   group 'Subforum Bulb' in the Admin CP 'Configuration'.

 CUSTOM ICONS

   You will also need to upload new icons to your images folder.
   This plugin ships with a set of icons for the standard theme.

   The icons distributed with this plugin were generated using ImageMagick
   in a Linux shell. This is the command used to generate the icons. If you
   have custom icons you may generate the missing ones with something
   along these lines:

     for a in on off offlock
     do
         for b in on off offlock
         do
             # reduce original icon to half the size:
             convert "$b".gif -resize "11x11" tmp.gif
             # add the half sized icon in the lower right corner:
             composite -geometry +11+11 tmp.gif "$a".gif sub"$b"_"$a".gif
             # same for mini
             convert mini"$b".gif -resize "8x8" tmp.gif
             composite -geometry +8+8 tmp.gif mini"$a".gif minisub"$b"_"$a".gif
         done
     done

   After that, upload sub*.gif and minisub*.gif to your images folder.
