I guess most of us newbies flood this forum with questions about settings/features that gOS devs integrated from AOSP without actually touching anything from it. So either
- they aren't knowledgeable over some particular function,
- either they won't fix it as it's not their priority / as AOSP devs will probably fix it themselves on a future release anyway
Therefore to reduce the amount of questions, or simply (better) to not reduce it but rather for knowledgeable people to answer more/faster to the topics they can at a single glance, i think it would be useful to differentiate, within settings, the font color of the features that are only in gOS. Then we newbies could be certain that we'll likely get help here for some feature explanation, or we'll know to straight enlarge our research scope to other websites..
And since it would require some frequent catch up, if AOSP integrates them in their base, etc
