Custom Settings feature has remained unchanged for a long time now. You’d say ‘why change something that works so good?’. Absolutely! But are you using them correctly?
To me it’s been a long time since last time I visited the Custom Settings documentation. So I dived into it and the truth is that, it took me a couple of reads of the Custom Setting methods docs to get all the details.
At the end Custom Settings are quite easy to use once you play around a bit with them, but have some secrets you must know! I got fun finding them and I hope you do too!
