Maybe the solution is obvious, but is there a way to expand the “header” portion of tracks and buses horizontally? It would be nice to expand all of them horizontally with the click and slide of a cursor so I can easily see all track names in full.
While not exactly what you asked for, there is setting “Track name ellipsize mode” under Preferences → Editor. So you can choose which part of the track name is hidden in the header. You seem to have it set to “Ellipsize end of name” but it can be changed to show other parts of the track name (which are often more important).
Yes, I am aware of this option, and it is included in Ardour 6 (-6.9.0 at least).
Thanks for the reminder, though! It certainly can help in some cases.
