### UI Enhancements
In this example we update the Shiny Text application with some additional controls and formatting, specifically:
* We added a `helpText` control to provide additional clarifying text alongside our input controls.
* We added a `submitButton` control to indicate that we don't want a live connection between inputs and outputs, but rather to wait until the user clicks that button to update the output. This is especially useful if computing output is computationally expensive.
* We added `h4` elements (heading level 4) into the output pane. Shiny includes a variety of functions for including HTML elements directly covering headings, paragraphics, links, and more.
