I actually develop this addon on GitHub https://github.com/bertvandepoel/sabconnectplusplus . So you are free to submit specific requests or even code to fix what you want to do there. I'm slightly confused about your use of provider, do you mean nzbplanet is an indexer? Feel free to supply more information as part of an issue on GitHub, so I can try to help you.

Also keep in mind that these reviews have a big impact on whether or not people will see my addon. In general this website considers addons with fewer stars to be buggy/broken or have other issues, and tends to suggest them later or to fewer people. So I suggest people use GitHub to let me know if something is wrong or missing, since when I reach out on here, I don't always get a response and then the review also never gets revised.
