Hi @Kev-Roche! Thank you very much for this contribution. As the addon you are improving does not have a declared maintainer, I take the opportunity to mention that you can consider adopting it. To do so, please read the maintainer role description, and, if interested, create a pull request to add your GitHub login to the maintainers key of the addon manifest.

Work seems legit. @sebastienbeau Do you want to update the review and we get this merged?

[leemannd]

@Kev-Roche Do you have time to rebase your branch? the goal would be to fetch the latest changes and allow runboat to be triggered.

[Kev-Roche]

@leemannd thank you, I rebased it.
