If I want to edit an artist info from the right panel (play queue) the artist page is opened in the middle panel > edit > download infos via plugins.
1) If I use "download > all plug-ins" in my perception only last.fm is used
Than I have to click "discogs" separat. If I dowload content from last.fm, change some points (e.g. additional paragraphs) and use then discogs plug-in HMM uses also the last.fm-plug-in and overwrite my additional paragraphs so I have to insert it again.
2) If there is any content in the biography field it will be overwritten after dowload > save > re-open the dialog field > downloading.
Maybe it should be better to fill only blank biography fiels?
3) Lyrics plug-in doesn't work.
