* mkvmerge: tracks in the destination file will now be sorted by their type
automatically unless the track order is specified with the `--track-order`
option. The order is as follows: video tracks first followed by audio &
subtitle tracks with other rarely used types of tracks last. Tracks of the
same type will be sorted in the same order as their source files occur in
the command-line arguments. Note that this doesn't affect file
identification. Implements #3545.
* MKVToolNix GUI: multiplexer: the default list colors used for distinguishing
source files does not include the darkest tier anymore (the ones where one
or two components are set to the value 0x3f) as they're hard to distinguish
from each other. Only affects new installations, or when the user presses
the "reset to default colors" button. Implements #3533.
* MKVToolNix GUI: multiplexer: the GUI will now check the state of the 'track
enabled' flag of all video, audio & subtitle tracks when starting to
multiplex or adding a job to the job queue. If there's no track with its
flag turned on for a type, the GUI will turn on the flag for the first track
of the type. This behavior can be turned off in the preferences. Implements
#3535.
* MKVToolNix GUI: header editor: the columns in the tracks/attachments view
and the values on the "track type" page will now be updated each time a
corresponding property is changed (e.g. when a track's name is changed)
instead of showing what's in the file on disk. Implements #3554.
* MKVToolNix GUI: macOS: when you install the application from the DMG it'll
register itself as an alternate handler for its supported file types. This
allows the use of the "Open with" context menu action in Finder.
* MKVToolNix GUI: Windows: a new settings in the preferences lets the user
chose whether to use the light or the dark color palette, or to follow the
system settings. Part of the fix for #3528.
