I already asked to put this plugin in the plugin-index from calibre, so you can select it through preferences within calibre.

Thank you for notifying. That is related to the update 0.2.0, it contains a wrong version of the config file.
There is a new update available v.0.2.1 with the the correct version.
Version 0.2.1. is available at the start of this thread.
Thank you for notifying, Very helpfull.

By the way, just using the search phrase https://www.buecher.de/suche?sq=9783159609751 does find the book.

This one was more difficult. I didnot get the error myself.
But I used an old config file for the new plugin.
It was outdated because PyQT4 is already deprecated.
So I made an new update with PyQT6, available in version 0.3.0 ( at the start of this thread)
Thanks again for testing.

Perfect, downloading metadata now works fine on macOS too.

I have found one bug, that isn't that important, but I wanted to mention it anyway. It happens when you press this link:



It'll open this invalid page:

This would be the correct link:
