[Idea] Add/Paste Cover Art with replacement

I've been using this software for a few years. I noticed that some files already come with album art that doesn't satisfy me for reasons like the cover either wrong or the quality is not good enough. Which means I have to remove the cover and then add/paste the cover I want.

I thought this process would be a lot easier if there was function to Add or Paste the image and replacing the existing cover at the same time.

And one more thing I just thought of while typing this up. I wish it was possible to paste the cover image by selecting the cover box and pasting using the good old Ctrl+V.

Thank you.
