Comment # 2 on bug 1139523 from Stefan Hundhammer

There is always a tradeoff with those column widths.

I agree that for me personally the package summary is the most important
column. But there were those who insisted that the version number was the most
important and that it should get more priority.

The version number can grow to insane sizes if package maintainers include Git
SHAs and/or timestamps or whatever in it. That is more likely in a view like
the "installation summary" because there is simply a much higher number of
packages in that list (the column widths are adjusted dynamically).

In the first few versions we had completely dynamic column widths, but that
means that one single item with excessive width makes the whole column grow out
of proportion, so the horizontal scroll bar becomes very wide.

If we set a maximum width on such a column (not sure if and how well that works
with the current Qt version) that means the user has no way to make the column
any wider which is also bad UI behaviour.

I agree that the current behaviour is undesirable, but there is no easy
solution.
