With iPhoto 9.4.3, Apple has enhanced the consumer-level photo management app’s Photo Stream support and fixed a handful of bugs. Photos can now be deleted from My Photo Stream by dragging them to the Trash, you can use File > Export to export photos from Photo Stream, and raw images manually imported from My Photo Stream are now editable. On the bug-squashing side of the equation, one fix prevents manually rotated photos from appearing unrotated when shared to Photo Stream, another addresses a crash when syncing to Facebook, a third prevents calendar text from appearing at the wrong size and resulting in order cancellation, and the final one fixes a problem that could cause books to have an incorrect number of pages after rearranging two-page spreads.

Untrash the Trash
Feeling trasher's remorse? On Snow Leopard, you can open the Trash (click the Trash icon in the Dock) and "untrash" individual items there. Select one or more trashed items (files and folders) and choose File > Put Back. This returns the items to where they were when you originally put them in the trash. The keyboard shortcut is Command-Delete - the same as the shortcut for trashing an item in the first place, since in deleting something from the trash you are untrashing it.
