the screen is a bit small for this really …
a while back a wiki was created with a good overview of patches (its not full up to date)
(most of the work was done by @healthylives 
)
that said, the patch manager (wifi/web browser) is becoming more prominent these days, so this could be a contender to display information about a patch - assuming patch developers writes some notes 
that said, i’ll be honest, with so many patches available these days, the way i work is to only keep installed the patches Im using… so i know what they do.
I then just go to patch storage on a ‘fishing expedition’, if i want i feel like something new
