When you have a file with a long name part of the UI gets hidden so you cant delete objects.
I suggest the name should be abbreviated if it gets too long, or at least then the window scale. There is a horizontal scroll bar but people generally have much bigger screens than 1200 pixels so I think you should be able to scale that a bit higher to take advantage of wider displays.
Maybe one could customise what columns they want display to save room? For example I dont really need to know the file size or number of lines.
