No folder conversion support
Does not support all WMA files for input. In particular, not does not support WMA lossless.
You cant drop a folder into this app, instead have to drop files. A pain if you have many subfolders, like I do. As a workaround I used Finders "search", restricted to current folder, thus flattening the tree and getting one huge list with all files.
The app does not report estmated time to completion.
Aside from these problems, it has converted my FLAC files into AAC files.
