From Andrei Doubrovski:
As you probably know, Photoshop Elements has not inherited all of the essential features of the full Photoshop. Some functions have been removed, while the others just stay hidden. The surface functions are quite sufficient for a beginner. As you advance, though, you may miss one or another undocumented feature.
Elements+ is a handy patch revealing the hidden functions in your Photoshop Elements. The bundle includes 152 actions sorted to 11 categories: Color and Tone, Selections, Layers, Masks, Smart Objects, Smart Filters, Paths, Text, Languages, Interface, Utilities.
To apply a revealed command, you choose appropriate tab in your Effects palette and double-click action pictogram. Detailed info on each action available in Elements+ Help file.
Package includes installer and uninstaller.
