like to add detection for Itanium and ARM systems, but I have no
way to test such changes.</li>
- <li>The code could be more flexible in its handling of the sizes of
- various graphical elements, and particularly drawn text. Prior to
- version 0.2.2, submenu text was invisible on UEFI-based PCs with
- 800x600 and smaller displays because of an inability to properly
- crop the graphics fields that hold the text. With version 0.2.2,
- I've put a band-aid on this problem by reducing the field size so
- that it now works on 800x600 displays, but smaller displays still
- suffer from this problem. This is just an example of the
- inflexibility of certain layout issues within rEFInd.</li>
-
<li>Although the ICNS file format used by rEFInd supports multiple
image sizes, if a size that rEFInd needs isn't present in the file,
rEFInd can't use the icon. The ability to scale images to the
desired size would be useful.</li>
+ <li>A way to set the color of the font would be useful for theming
+ purposes.</li>
+
+ <li>The program's font features could be greatly improved by enabling
+ use of a standard font format, by enabling use of non-ASCII
+ characters, and by enabling use of variable-width as well as
+ monospace fonts.</li>
+
<li>I would like to be able to specify the volume on which a boot
loader resides using a partition GUID value, but extracting a GUID
from the partition data is harder than extracting the volume's
substitutes the size, so you get displays like <tt>boot
EFI\foo\bar.efi from 90 GiB volume</tt>. I'd like to add more
checks to substitute the GPT <i>partition</i> label if the
- <i>filesystem</i> label comes up empty, or add a filesystem type
- identifier to the size.</li>
-
- <li>The default_selection option in refind.conf could be improved by
- supporting a list of default options, so that if the first item
- isn't found, rEFInd will try to boot the second one in the list,
- and so on. This could be handy in case a driver fails to load, or
- to provide an override in case the user inserts a specific

and/or initial RAM disks relative to the rEFInd directory (or the
boot loader's directory, in the case of initrds).</li>
- <li>Various options (<tt>dont_scan_dirs</tt>, <tt>also_scan_dirs</tt>,
- <tt>scan_driver_dirs</tt>, etc.) refer to directories or files,
- either on the ESP or on all partitions. A way to identify specific

</ul></li> <!-- Improvements -->
<li><b>Known bugs that need squashing:</b>
<ul>
- <li>When in Secure Boot mode, rEFInd can launch just one driver that's
- signed with a shim key or MOK. The second and later drivers
- generate "access denied" errors. <!-- I think this is because of
- the fast-and-loose sample code I borrowed from shim, which re-uses
- rEFInd's own image handle (the <tt>image_handle</tt> variable in
- <tt>start_image()</tt>) for launching shim/MOK-signed binaries. The
- result is that when the second driver is loaded, it can't register
- itself with the firmware because the firmware believes it's already
- been registered. The solution is likely to involve creating a child
- image handle rather than re-using rEFInd's own image handle, but
- this is likely to be tedious to do—see
- <tt>/usr/local/UDK2010/MyWorkSpace/MdeModulePkg/Core/Dxe/Image/Image.c</tt>
- for the reference UEFI implementation. --> </li>
-
- <li>When setting a resolution higher than about 800x600 (or maybe even
- 640x480) in text mode, the text displayed by rEFInd, and on some
- systems shells and other programs launched from rEFInd, is
- restricted to an 80x24-character area in the top-left corner of the
- screen.</li>
-
<li>The <a href="http://www.rodsbooks.com/gb-hybrid-efi/">Gigabyte
Hybrid EFI</a> has a bug that causes the allegedly case-insensitive
<tt>StriCmp()</tt> function to perform a case-sensitive comparison.
implementation, and a dismal one at that, so I'm inclined to just
let it go.</li>

+ <li>The Shutdown option works correctly on Macs, but not on many UEFI-based
PCs. On such systems, Shutdown reboots the computer. This should be
fixed.</li>
<li>The code is in need of review to search for memory leaks and
similar problems.</li>
