Create your own Unity Package Manager (UPM) package to extend the functionality of the Unity Editor.
You can use packages that you create for one of your projects or for multiple projects. You can also share your package with others in your organization or studio so they can use it in any project. You can even distribute your package through official channels, for the wider community to use.
