Interesting effect with the Thumbnail image when freezing one column and then scrolling right. The image slides over the frozen column data. I like it!
What is not so neat is that when I create a set of three frozen columns, [Artist] [Name] [Track #], when I scroll right the heading of the [Name] column is covered by the names of the columns scrolling from the right. So I can no longer see the "Name" column heading, but I can see the "Artist" and "Track #" heading.
When I want to freeze more than one column, I have to remember to do it is the reverse order to what I want to see once I have finished freezing columns, as a new frozen column always goes to the far left. I can drag and drop frozen columns, but then they lose their frozen state and just stay to the right of the remaining frozen columns.
In fact, all columns to the right of where I drop a previously frozen column are unfrozen.
It would be nice if frozen columns could be dragged into the order I want on the left, and would retain their frozen state.
