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 function.

"Elements+" is a handy patch revealing the hidden functions in your Photoshop Elements. The bundle includes up to 145 actions sorted by category. To apply a revealed command, you choose appropriate tab in the Effects palette (screenshot) and double-click action pictogram (screenshot). Detailed info on each action available in Elements+ Help file.

The patch is available for all versions of Adobe Photoshop Elements. Still, the feature sets could vary.
