Hello community,
Where can I download the portable version with the “old” interface ?
NOT the one with the black left menu…
Thanks.
Welcome!
What “old interface” are you talking about? The “mkvmerge GUI”? That program was retired in 2015. It won’t come back.
Hi,
Before the 80.0 or 81.0 (I don’t remember), I had a simpler one, without this black menu…
Uhm, no — there has been significant UI change in the last couple of years.
What you can do is disable the tool selector in the preferences.
I honestly have no idea what you’re talking about.
OK, my bad 
After research, I found out that what I got in mind is another GUI…
Sorry for the disturbance…
That explains things 
No problem.
