As you, probably, know, Adobe 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" Photoshop Elements functions are quite sufficient for a beginner. As you advance, though, you may miss one or another undocumented function. Here "Elements+" will be of service to you.
The thing is that by no means all the absent functions are removed from Photoshop Elements (hereinafter, "PSE") in full, many of them are just hidden from the user. And "Elements+" (hereinafter, "E+") is a handy add-on that lets the hidden functions out. There are E+ kits for all the PSE versions.
Elements+ comes to you with an automatic installer, so, you needn't follow tricky instructions and copy dozens of files to different locations manually.
