At the moment, we're able to set the following Matroska flags in MakeMKV:

d = "Default track" = yes
f = "Forced track" = yes

But could we also have the ability to set:

c = "Commentary track" = yes
e = "Track enabled" = yes
h = "Hearing Impaired track" = yes
o = "Original Language track" = yes
t = "Text Descriptions track" = yes
v = "Visual Impaired track" = yes

I'm not sure if any players even respect these flags but I figure that they must be there for a reason?

I think most of those flags are MKV version 4 items. I think MakeMKV outputs MKV version 2 files, where those flags aren't defined.

Hmm... Okay, new feature request: Could MakeMKV be upgraded to output Matroska version 4 files?

And before anyone comments, yes, I know these flags can be set using the MKVToolNix Header Editor. That's where I have been adding them, but my old PC takes forever to open an UltraHD movie in MKVToolNix, and as long again to save any changes!

I just thought it'd be nice to be able to set them within MakeMKV during setup and not have to worry about the additional work afterward.
