- rEFIt's original design, and hence rEFInd's design, enables easy
-theming by replacing icon files. If you'd like to design a new theme for
-rEFInd, feel free to submit it. I might or might not replace the icons it
-uses now (most of which come from the Oxygen Icons package), but I may
-provide a way to make selecting a theme from one of several installed
-themes easy, and provide links to themes on this Web site (or even host
-them on the project's Sourceforge page). Note that rEFInd currently
-supports only BMP format and ICNS format graphics files, and the former
-aren't very useful for icons because they lack transparency support. ICNS
-is an Apple format, and many Mac tools support it. In Linux, you can
-convert PNG images to ICNS format by using the libicns library's png2icns
-program. I'm not sure what you'd use in Windows to create ICNS files.

-- 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.
-
-- 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.
-
-- I want to be able to specify the volume on which a boot loader resides using features other than the filesystem's name/label. I used the label because this feature was easily extracted from the data structures that rEFInd maintains (inherited from rEFIt). A number would also be fairly easy to implement, but would be arbitrary and therefore difficult to predict. A partition GUID value would be good, but extracting a GUID from the partition data is harder than extracting the volume's label.
-
-- It would be useful to be able to specify paths to boot loaders and/or initial RAM disks relative to the rEFInd directory (or the boot loader's directory, in the case of initrds).
-
-- There's currently no way to create a manual boot stanza for a BIOS-booted OS. This isn't a big priority for me personally, but I can see how it could be for some people.
-
-- Returning from a program (such as an EFI shell or a boot loader that fails) produces an error message about a failure when "(re)opening our installation volume" on some computers. (Among mine, only a 32-bit Mac Mini produces this message.) This seems to be harmless, but I haven't removed the error message because I don't fully understand its cause or why it doesn't appear on most systems. This needs investigating and fixing.
-
-- The Page Up and Page Down keys work in a rather strange way—a result of an admittedly quick fix on my part to a problem with a data structure that makes implementation of scrolling harder than it ought to be.
-
-- I'd like to find a way to enable users to enter customizations for boot options and then save them to the refind.conf file.
-
-- It should be possible to override specific auto-detected boot loader settings—say, to disable one specific boot loader or change its icon.
-
-- A way to read boot options set via efibootmgr, bless, or similar options from NVRAM to add to the boot set would be useful.
-
-- A way to examine and change the NVRAM settings could be useful. This would enable a CD-based boot of rEFInd to fix a broken disk boot. Perhaps this could be done via a separate tool that could be launched much like the shell or gptsync.
-
-- I'd like to find a way to get rEFInd to launch BIOS boot loaders on UEFI-based systems. This option currently works only on Macs—or at least, I've not gotten it to work on any of my UEFI-based PCs.

+- The Gigabyte Hybrid
+ EFI has a bug that causes the allegedly case-insensitive
+ StriCmp() function to perform a case-sensitive comparison.
+ This causes any number of bugs in file matching. For instance: Changing
+ the case of icon filename extensions (or various other parts of icon
+ filenames) causes icons to be replaced by ugly "generic" ones; and
+ rEFInd sometimes appears in its own menu (the firmware sometimes
+ returns an all-caps version of the filename, but other times returns
+ the filename with the correct case, causing a mismatch if the path
+ includes lowercase elements). Some of these problems can be overcome by
+ converting both strings to be compared to one case before doing the
+ comparison, but others aren't so easy, since I think StriCmp()
+ is being called internally to the EFI. In any event, it'd be nice to
+ fix some of these problems. OTOH, this is a workaround for a bug on
+ just one EFI implementation, and a dismal one at that, so I'm inclined
+ to just let it go.

+- I've received queries about rEFInd's ability to work with Apple's
+ whole-disk encryption scheme that's new with OS X 10.7. Unfortunately,
+ I lack the hardware to test this.

+- The Shutdown option works correctly on Macs, but not on UEFI-based PCs.
+ On such systems, Shutdown reboots the computer. This should be
+ fixed.
