Opening Examples: confusing ux

Beginne damit, den File > Examples-Workflow im PDE nachzubilden, einschließlich der Kategorieauswahl, der Beispielauswahl, des Doppelklickens und der Schaltfläche „Add to Examples“. Überprüfe das Verhalten von Examples List / Loader und verständige dich auf ein Interaktionsmodell; die Arbeit ist abgeschlossen, wenn neue Benutzer herausfinden können, wie sie ein Beispiel öffnen, ohne dies mit dem contributed-example loading zu verwechseln.

Enhancement details

Hello, I am a new Processing user (but I have been using p5.js and doing web development.)
Here is an issue I am having during my first time using the latest Processing Editor.

TLDR
The interface with the button at the bottom makes it look like form selection and unexpected that double click is required.

What Happened:
I want to open an example.
I click File > Examples.
The list of examples opens in a window.
I click a category. It just highlights, but I expected it to show submenu on click or hover
I click the little icon to unfold a category.
I click a specific. It just highlights, but I expected it to open.
The only thing left to click was the "Add to Examples" Button at the bottom.
Clicking "Add to Examples" opens the Contribution manager examples tab.
I couldn't tell why the example I highlighted in the list was not present in that list, or why the lists were different.

After a couple rounds of trying the same thing and reopening the project, I finally understand that I need to double click to open, and that the "Add to Examples" is a way to load in from the Contributed examples.

Impact:
Makes new users who don't catch on may easily give up or be embarrassed to ask for help.

Enhacement Ideas:
The example list should function similar to other programs so new users can easily catch on.
Option 1: Either having single click so it's like the menu item is an action being executed.
Option 2: Another option is to have a button that can open the example so you are acting upon your selection.
Option 3: Style it more like a file-explorer grid so double-clicking is more expected.
Option 4: Any ideas?
