It doesn't work in the main panel, though.
How do you see it working in the main panel?
Details in the main panel are displayed - in one way or another - in a grid or list.
In each of the following examples, it wouldn't make sense for any of the selected items to have a variable number of rows.
Why could it not be useful?
I often find that the title plus the author, who often has many collaborations, does not fit in the line.
You could put a condition that if the number of characters is greater than e.g. 10 put the text in the next line.
For example: this visualization has very long titles.

And there is no author because it is always the same for the whole album but if each track had it different at the end it would be cut off.
See how it is displayed on this panel?

By the way, the possibility has been given to change the size, bold, italics, color, of the font in the virtual tag, as I did in the example I put in the image, so I think it is limiting to use MB only as a mere dot matrix printer printout.
You see there are users who use applications for 10% of their possibilities, because that is enough for them and they don't feel like exploring them for other possibilities.
I didn't know that by putting a ; to head in the headers of the info tracks panel. Now that I have learned about this possibility I have created an info track as I wanted.
So if it is not too complex, why not add this feature?
