A small update with new version v1.5.1:
http://sourceforge.net/projects/gmkv....1.7z/download
Changelog- Increase the drag and drop area for the input file to the group box of input file info
- Add a context menu for easy selection of tracks
The batch button of MkvExtractGUI-2 is not one of the features that I will add, since I am designing a true batch mode, or rather a job management mode. But this will be in the v2.x series of the app and I can't make any promises about the release date.
