This is some small stuff, but I thought I might as well mention it. I noticed that when you auto-resize a column by double clicking on its column separator (like in Excel), what happens depends on what content is showing for that column on screen. That is, if any of the cells for that column that are visible on screen have content, the resize takes place as it should, the column sized to the width of the widest content. If all the currently visible cells for that column are empty, the resize will happen as though the whole column is empty, ie the column will resize to "barely visible".
As I say not earth-shattering stuff but thought I would mention it while I remember.
