replace/replace all funtion

When making a playlist some people (like me) choose to add jingles directly to it.
With a big playlist there are also many jingles with the same name that play more then once. If I want to replace some jingles for a new one and with another tilde (~) I have to do it all manual.
It would be nice if there was a search and replace function in Raduga.
Ofcource it is also possible to edit the playlist with a texteditor that has that function.
