I thought I found an answer but now it doesn’t seem to be working… What I want is a folder that when it is open, has one row of items. The widow should be one row with, say seven columns. But I want the virtual container to be a single row as well. If I move, add or remove an item, I want the other items to move strictly horizontally to adjust. If I sort the item, keep them in one row.

I used folder Settings > Current Folder Window and set width to 2000, the max, and the height to 260. Then I goto Layout and set Number of Columns to 7 and Size of Rows to 260. Finally, I go to Misc and uncheck Rearrange Items.

This does what I want MOST of the time, but everyonce in a while, everything get organized into 7 cols by n rows, n>1. It does this when I sort items, and I think, when I change certain settings.
