I might be late to the party, but first noticed this the other day on ST9.
In the 'Edit Links' window you could never see the file you wanted to edit the link for unless you expanded the column to the end and then scrolling across EVERY TIME. Painful....
From memory someone said this was due to the technology used for this particular window, or what it was editing, and it just wasn't possible to make the window larger.
Now though there is a summary of the file and path at the bottom so you CAN see the file without expanding the column. This makes such a difference when you have a lot of links to edit and is very welcome.
