Any updates yet, NEMO? And the links no longer works.
An option to keep the search string in search box would be great. So it would be easy to alter the search string and search for a track that is named a little bit different.
Another interesting option would be to define character groups whose elements are treated as similar characters when searching. For example searching for "Tiesto" would also find "Tiësto".
In searchbar preferences select "Append search string to playlist name".
I wonder if is possible to create a new playlist for every search.
