I have built VS Utils [1] mostly for myself since I work with WordPress and they use serialize(), unserialize() functions a lot, and sometimes I need to convert base64, timestamps value without leaving the editor. I find it's easier to write an extension for daily use functions and publish to VS Code so I can download it easier, sync across devices. Hope it helpful for others too.
