I'm not a great expert on the matter, because I'm pretty satisfied with how Nickel works (I added Dropbox support, but that's not done with a patch, NickelSeries, NickelMenu and NickelClock, but the last three are proper add-ons, so no patches again), and it's been a while since I looked closely at them, but you can find more info; - on the github page of the guy maintaining them all https://github.com/pgaskin/kobopatch
