No kidding. Once you click Save, Kid3 applies all changes in an instant, and there's no going back on it. But that's perfect if you're in the mp3 sorting business. With Kid3 you can edit and transfer information between the filename and tags.
Kid3 displays all audio content from a specific folder in a list. Clicking on one or selecting more items from the list will show their metadata on the right panel. If files feature both ID3v1 and ID3v2 tags, then both will be displayed separately. After changing a field, the change will be signaled both on the field space and on the item on the list. Mistakes can be corrected by clicking on the Revert button. However, that will undo all of the pending changes. So you should probably often save while editing.
You can exchange data between tags of the same file, and you can also use tag data to re-name the files and vice-versa. You can use special tags to designate how the filenames relate to meta tags. The interface is a bit too unpolished for my taste, but things work as they should.
There are also several options for importing tags from Internet sources like Amazon or gnudb.com. What's more, you can acquire cover art by letting Kid3 open an Internet Explorer window and do a search based on tag artist and album. It's very archaic, but it also works.
If you have no other option, you can use Kid3 to create m3u playlists as well as play the media files that you have opened.

Kid3 is a functional program, but it looks like it has fallen behind the times. The interface is a bit awkward, and some online features have not been updated. Its primary advantage is that it does not need to be installed, which makes it a portable application.
