I was thinking about a new field in playlist menu like this:


It happens many times to me that I would like to listen to all tracks that I have, from certain artist, which is currently being played.
This can be done now by copying artist text and pasting it into collection search field (collection browser) and then append the results (or by creating custom smart playlist).
So I thought about adding such search directly into playlist context menu. This could be also applied to other fields, like album - you right click on certain track with album field displayed, select append more tracks from album "sample" and amarok would automatically do that for you.

What do you think?
