Great App! I've been using her for years, with the recent OS X El Capitan changes some things are now broken like Repair Permission. Also would you be willing to add the option for installing Kext Extensions into /Library/Extensions/ along with /System/Library/Extensions/ and Extra and Extensions.mkext on Desktop? Kext Wizard would then be able to do-it-all, you could even add the option to install Kexts into /EFI/clover/kexts/10.x/ folders if you wanted to just go completely overboard.
Obviously this can all be achieved manually with terminal but your Apps a heck-of-allot easier!
