Here is an idea which I think would be good to implement sometime in the future - not urgent, just whenever it is practical.
At the present time, when you open the App Browser, you get a list of extensions. Some of these are apps, and others are dependencies.
I suggest, have some way to differentiate between apps and dependencies, and have only apps listed in the App Browser, not dependencies. (Still have dependencies listed in the Depends and Size tabs)
That would make it simpler to find apps.
The same thing could be used with removing apps.
You may include the option to list all extensions, for those who want that option.
