Desktop Background Tuner is my latest work. It allows you to change few hidden registry settings of Desktop Background feature in Windows 7 and Windows 8.
With Desktop Background Tuner you will able:
Add or remove items into "Picture Location" combobox. I will call them "groups" for simplicity, ok?
Add or remove folders to "Windows Desktop Backgrounds" group in Desktop Background settings.
Add or remove folders to any other group you have added in "Picture Location" combobox.
Add personal folder or add system-wide folder to group.
You can control grouping of images. There are several setting available:
grouping by file author
grouping by file comment
grouping by date
grouping by file extension
grouping by Mime type
grouping by file name (non-localized)
grouping by file name (localized with desktop.ini) By default grouping is set to localized folder name. Now you can change it.
You can change animation duration when desktop wallpaper changing. In other words, you can set speed of the fade effect transition. Note: this trick is not available for Windows 8. Microsoft has removed animation duration option from registry and this settings has no effect in Windows 8.
You can delete "Picture location" cache/history of Desktop Background option with one click.
