Well, now I got the library to display at last, I have used it for a while.

I hated the old library and I wanted something different and they have given us something different and I am not sure if it massively better.

The old library was "clunky" (technical term, that). The navigation was poor, having to scroll up to the top of the items in a folder to double-click the up arrow was the worst. What it needed was "up one level" button that was visible at all times. This would have gone a long way to making it a lot more usable.

One thing I did like however was the ability to size it wide and tall and so see a lot of thumbnails at once, often the whole content of a folder was shown on one screen although the text didn't wrap below the icons and this often made it difficult to choose between very similar items.

The new library, it has been noted, needs the ability to display all icons large. Without this the user has to do way too much clicking to decide which item they need. I beleive this will be fixed in the future.

However, my main point is that the new library will, as it is now, never show as many items on the screen at once as the old library (assuming the old library was resized). Resizing the new library simply makes more empty horizontal space and the items shown are still in a column down the left-hand side.

I am guessing that it is not possible program the library to display multiple columns of content in the new tree view, I would be surprised it it is. In this respect, the old library was better than the new.

Sorry.
