There are several ways to get the cover art into a track.
As it happens, when I tagged a number of albums, I had a mixture of sources for the albumart files: some in the folders where the album resides, some had to be extracted from the internet.
Now: when I use the extended tags dialogue to get the album art from the folder, this is ok if there is a file.
If there is not, then I have to close the file selection dialogue, close the extended tags dialogue, open the tag sources dialogue, select the appropriate tag source.
My wish would be to incorporate the tag sources menu as a drop down list or something in the extended tags dialogue so that I do not have to close all the dialogues to access the tag sources.
I do not ask for extra functions, just a shortcut.
