Photoshop can finally save files in the background! This means that you will be able to keep working, in Photoshop CS6, while saving the file. You no longer have to wait for long file saves to continue working. Yeah!
The Photoshop CS6 Beta (Free Download Here) has this option in Preferences>File Handling.
When checked, and a file command to ‘Save’ or ‘Save As’ is initiated, the event will occur in the background. Yeah! A progress bar appears in the lower left corner of your document window letting you know that the save is going on, and how far it’s gotten.
