is a simple and easy to use MP3 editor. Its main advantage is that it works directly in the MP3 format without having to decode/re-encode, so it is very fast and doesn't degrade the music quality

changelog:
Added option to insert the track time into the file name when saving an MP3. This is useful if your standalone MP3 player doesn't show the track times but just the track names.
Added a little marker on the volume bar when normalizing. The marker is not shown by default, but you can just click 'auto' and it will show up. Moving the volume bar to the right of the indicator means that the file will get clipped. Moving left is safe
