Dear developers, I wrote a very small patch (2 lines), to prefill a new playlist name with the name of the folder it was created from. Here it is: http://www.rockbox.org/tracker/task/12104 .
I talked about it on IRC, and the people seemed to enjoy the idea, but they advised me to post on the ML as it was a "change in behaviour". Do you think this patch is a good idea? If it is, can someone commit it?
