Refresh album art for a single folder

I would like to see a feature to refresh the cached album art of a single folder (and its subfolders). At the moment, one can clear the album art cache globally, which requires the WHOLE library to be rescanned - wastefiul, if only a couple of albums from thousands have updated album images. There is an UPDATE option in a folder’s context menu on the BROWSE page, but it does not update the cached images in the folder.

I’m fairly sure the update option does refresh the album art, but you need to refresh the web page (press F5) to see the updated image.

Thanks. Yes, sometimes the browser cache displays the old albumart - a CTRL+F5 clears up the problem. But not always …
