The opened functions appear in PSE immediately after the successful E+ installation. Except perhaps by the first run you will need to wait a second while the program reconstruct its cache file. The unleashed features can be accessed via dedicated dialog boxes that include undocumented commands and panels for exploring and using the hidden (officially unsupported) contents, such as paths, color channels, and more. The kit includes smart filters, vector masks, and many more advanced tools normally hidden under the hood.
Furthermore, the "Scripts" catalog lets users automate tedious repetitive operations, create complicated effects, extract EXIF data from photos, etc.
Elements+ comes to you with an automatic installer, so, you needn't follow tricky instructions and copy dozens of files to different locations manually.
