Idea Summary
Currently, there are only 4 individual Sample apps and the Universal Theme that are ready to run -

If we want to explore techniques and features of APEX in the starter/sample apps, the only way is to install these apps into our workspace which take up storage space and also clutter the workspace.
Use Case
Quickly run a sample/starter app to explore features without having to install them in our workspace and we don't have to keep upgrading them manually.
This single demo app with all the sample/starter apps can be hosted somewhere like -
https://apex.oracle.com/demos
Another idea is to separate them into 2 apps (or have all these 3 options) -
https://apex.oracle.com/starter-apps
https://apex.oracle.com/sample-apps
However, sample/starter apps installation option in the workspace can still continue to exist so that if we need to look into the code, we can install them inside our workspace.
Preferred Solution (Optional)
Having a single app (or 2 apps as suggested above as an alternate idea) with a menu system to quickly launch various sample and starter apps would be nice and convenient. A single app can serve all the developers and also save Oracle from having to maintain thousands of apps installed by developers and save on storage. Also, this app would get upgraded automatically with each release of APEX.
