Yes, that's the fault in my expectations. I was expecting it to automatically 
resize the columns but within the limits set by the window. As a programmer, I 
guess that this would be very hard to program in a way that it works correctly 
under all corner cases.

Wrong expectations, see above.

Wrong expectations, I was assuming that Thunar auto-adjusted when resizing the 
window, but as you said it only adjusts to the required size of the columns.


Thanks for the quick feedback!

Exactly the opposite, if you read the help text. That means the columns
are expanded so the text is visible. So yes, that might means
overflowing the window.

Yep, same here.

Yes, something like.

I don't have any opinion on this :)

Why?

That's pretty not clear at all. Care to explain?

I don't think so, it looks completely Thunar-internal.
