MKVToolNix 8.3.0 brings mostly enhancements to the MKVToolNix GUI (Graphical User Interface) component of the software, but also some much needed under-the-hood improvements that make the application more reliable and stable. Among some of those MKVToolNix GUI enhancements, we can mention support for force-starting selected jobs in the job queue, improvements to the chapter editor, and the ability to display running jobs in the status bar.
