It also correct a bug of wrong image orientation (was wrong in the File Browser while good in the Editor tab) This patch also introduce several speed optimizations like: - switch between File Browser and Editor tab in Single Editor mode - asynchronous computation of the Batch Queue's thumbnails - quick start of RT even with a huge queue - less GUI overhead when applying a profile to multiple thumbs in the File Browser
