MKVTooNix – A couple questions

[Moralez]

1. When I close the application down after processing a few files I get the message:
The multiplex settings creating "<No destination file>" have been modified. Do you really want to close? All changes will be lost.

I have no idea what this message refers to. I simply click “Close Settings” and when I come back everything works fine. I cannot find any "<No destination file>" description anywhere under preferences. I see the Destination file box at the bottom of the application and it goes blank when the multiplexing process is finished. I need some insight on this.

2. When I load an MKV file into the Source file input box the tracks show in the bottom box. The old MKVTooNix I was using (v7.7.0) had a button to toggle all the tracks on or off. Under v85.0 I have to select a track then (ctl + A) to select all the tracks then right mouse click and select Disable all items. Is that the only way to toggle these tracks on or off?

1. It simply says this because you haven't specified an output file for the current multiplex settings. To avoide this simply go to Preferences -> Gui -> Warnings ; and disable "Warn before closing modified tabs"

2. Right-click anywhere in your "Track chapters and tags" box, and select "Disable all items" You don't have to mark them all first.

Thank you. Appreciate the help.

Once I've opened MKVToolNix I tend to leave it open, sometimes for days -- because I mostly hibernate Windows -- until I shut down Windows.

This message usually puzzles me because I've forgotten about having launched MKVToolNix days ago and that it's running in the background, so it's displayed out of context when you have been using many other applications. Quite surprisingly, today it even appeared during a Windows restart, which is even more out of context..

As implemented there is no clue as to which of my many Windows apps is involved.

SUGGESTED SIMPLE FIX:
This warning dialog box will be made meaningful merely by changing its title from "Close modified settings"
to "MKVToolNix - Close modified settings" which will put it in context no matter when it appears.
