UEFITool 0.18.4 / UEFIExtract 0.2.2
- added new FFS GUID found new in Apple EFI images - added PDR region parsing as BIOS space (Apple feature again) - changed default directory for saving to the directory containing opened file - focus and cursor position are now set properly for GUID tab in search dialog - search dialog resized to fit the whole GUID - codebase cleaned form unnecessary spaces
