@Bananaweizen : Oeps, thanks for notifying. I did not realize that changing the name in the code, would also change the name of the plugin.
(And that just because I did not like the capitalized identifier for the link;-)
Because I am not using the plugin myself and do the testing in my own environment, I don't use the update procedure. That is why I did not get any trouble with it. So thanks again.
About the title capitalization.
I took a closer look at my code, especially because goodreads returns without complete capitalization.
And yes, my code used a cleaning method of Calibre on the search-result and that function changes the captilization.
So you were right in that way, it is done in the plugin.
I made a dirty change, so now the original title of the website is returned.
(I did not noticed your second comment, but we concluded the same)
Please keep commenting, that's the only way to make the plugin more mature.
