Plax is wonderful. Thank you very much for creating it. I use it mostly for removing chapters from .mp4 files.
The one feature that would make life a lot easier is if there was a batch chapter removal feature.
1) Specify a folder or files that contain the .mp4/.m4v
2) Application opens, removes all chapters, and saves the file
3) Application parses through the entire folder or files specified in step 1
Not sure of the level of difficulty to implement this.
