Hi there! I have been using this software in a giant project of replacing old crappy MP3s with higher quality FLAC files. One issue I typically have is that my metadata, including embedded album artwork, is typically higher quality than what comes with the purchased FLAC. So I have to copy all of my metadata over.
For the artwork, that means left clicking on the old song, right clicking on the thumbnail, clicking Copy, then left clicking on the new song, right clicking on the empty thumbnail box, and clicking paste. Six clicks.
It's not a huge deal, but over the course of many hundreds of songs, any optimization in the workflow is a huge help. So here is my feature request. If a song is selected, and it's thumbnail showing on the left panel, I'd like to be able to left click and hold and drag the thumbnail over to the main list, to the new song, and then let go, and have it copied into that file as embedded artwork. Please see the attached GIF for an example.:
