I can only give you a couple of suggestions based on Windows 10. I have no idea how to do it with a Mac.
- In File Explorer, navigate to C:\Program Files\Adobe\Photoshop Elements 2020\ . Right click on the PhotoshopElementsEditor.exe file and choose Send to>Desktop (create shortcut). This will create a desktop icon that you can double-click to open the program directly.
- With the program open, right-click on the taskbar icon and select Pin to taskbar. The program will then always be available from the taskbar icon.
BTW, I assume you are asking how to avoid going through the Home Screen to open each individual program. It is certainly not necessary to open the Organizer in order to go to the Editor. You may also want to be aware that links to your latest edited files are found in the Home Screen. So, if you want to work on a recently edited image, you can click on the Recent Files links that are in the lower right corner of the Home Screen, and it will open in the Editor.
