N/m - answered my own question by just installing it. Actually took longer to ask the question than to apply the KUAL, lol. Trying the font fix now...
#----------------------------
This looks pretty cool. I'd like to install it, and also want the "hide fonts" button. Let me see if I've got this right before starting, maybe I can avoid a problem in advance.
I already have jailbreak and jbpatch installed, and I guess the dev certs is installed along with jailbreak (from update_combined-devcerts?). So now all I need to do is install the Kindlet jailbreak, and then copy the Kindlet azw2 file to the documents folder? And that's basically it? Or do I also need to install KUAL-specific devcerts?
Then for the hide fonts button, I just need to drag the fontconfig folder to the extensions folder, then edit the fonts.txt file to comment out whatever fonts I don't want? Sounds too easy, makes me think I'm missing something. Would appreciate if someone could tell me in advance if I've got it right, thanks. :-)
