The search window can be viewed in either Classic view (similar to LW 4) or else in List mode which is the default view. Click option top right of search results window.

The other windows cannot be changed. However, I believe a request of mine will be followed through which is an option to view image window in an alternative way. At present the image window shows no information, not even the file name. Simply the image thumbnails. I did suggest alternate views for the other windows too but I'm not holding my breath. lol

Some changes will be made in later LW 5 versions. And apparently a few old tools brought back into action.
