command

At README.md, there is a slack link:

Is it for public discussion for the project?

But the slack link shows "You need to sign in to see this page.", and I cannot sign up for this page(or workspace).

@spf13 please fix this.

Describe the bug
The first widget added to a UI will be skipped upon cycling.

To Reproduce
Steps to reproduce the behavior:

1. Start the UI, with a couple widgets added one after the other
2. Cycle widgets with the set key
3. The second widget is focused

Expected behavior
The first widget gets focused first, as it was never selected.

result.on(
  success: { 
    greet: -> (first, last) { puts "Hi #{first} #{last}!" },
    print_name: -> (last, first) { puts "#{last}, #{first}!" }
  }
)

Once #150 is done, add a way to set default switches something like

manager.getContexts().setDefaultSwitch(Residence.class, "res,residence,r");

Following the mindset of #21 - Let's consolidate workflows into GitHub Actions for the docker build process as well, given lack of configurability of the Docker Hub builder.
