Feature Request: Batch extracting album cover

Can i request a feature that can batch extract the album covers of all highlighted files?
And will be automatically renamed according to the source's filename.
It's too much work to manually extract each cover then manually rename it because the default name that appears is "folder".

It's already there.

Define an action:
Type: Export Cover to File
Format string for image filename: %_filename%

Even if you do it manually as till now there is no need to rename because you can define an imgae-filename in
Tools => Options => Tagsources
like %_filename% or any other tag or tag-combination.
