This is a WordPress plugin in active use. As such, you cannot change option names or option keys, you must retain upgradeability with these option names or keys. Note: ONLY THIS PLUGIN ACCESSES itself, upgradeability and backwards compatibility literally is restricted to any option keys used in the database and the format of the values. You do not need to retain compatibility with JS or PHP from previous versions as the entire plugin is moved forward each release.

Any development must be with this in mind - we are unaware of the plugin stack which will be installed along with this plugin, all we are sure of is that it will be WordPress.

NEVER EVER cover up errors. That means, if you add a try/catch block that is fine, but it should output the FULL ERROR including stack trace so we can bugfix more quickly. I HATE IT when errors get converted to things like 'unknown error' and it just slows us down, so really try/catch blocks should only ever be added when we know that this part might fail for a valid reason. This also means do not - unless specifically asked - implement fallback mechanisms for when things fail. I want to KNOW immediately when things fail, I don't want any cover up of any kind.

Please read the developer.md file to understand overall architecture if that file exists in the folder of any file I ask you to modify.

NEVER add any error handlers or belt-and braces or fallback mechanisms.

Always KISS, try to never duplicate code, always fix the root cause rather than the symptoms.
