[solved] Mystery Button

What does this button do?
Running patch 7

When you grab a column header (e.g. the Type header in your picture) you can move its location via drag and drop. You can also change the size of a column by dragging the separator between them.

The button appears, showing you the grid is non standard, and you can reset it.

So its a reset button?
I don't recall moving columns around.

Thanks.

Im just saying what you have to do to show the button that is hidden in that spot.

Move a column around, change its size. The button will appear in the now empty spot and you can press it.

After pressing it the spot will be empty like in your screenshot (the button only shows in that empty spot if the grid has changed)
