SDview at Mac App Store analyse

New feature: - Undo for image deleting (the single, most requested feature) has been added for all supported OS versions, including the venerable Snow Leopard ;-) On filesystems where moving files to Trash is not supported, an option for immediate delete is presented to the user. Fixes: - Order of image transformations (mirror then rotate vs. rotate then mirror) could affect how the image was transformed when reloaded later. - When deleting image(s) in random (shuffled) order mode, the sequence of images could get corrupted. - A dialogue box informing about invalid destinations for shortcut actions could under certain circumstances be shown on startup, even if those actions were already disabled. - Choosing "Show in Finder" when in full screen mode AND using "fast full screen" did not exit full screen leaving Finder windows obscured. - Transformed images with high DPI displayed with incorrect resolution in "Zoom to Fit" mode, leading to blurred picture being displayed. Misc: - Format of extended file attributes holding transformations information was changed to allow compatibility and interoperability with GNU/Linux (yes, we have one cooking!) version of SDview. Old format is still supported an automatically migrated on all image files, having it attached.
