Allow buttons to be displayed ordered vertically

[jorge-menjivar]

Currently, v1alpha1 doesn't have the option to order buttons vertically, and all buttons are ordered horizontally and wrap around. It would improve the readability of the UI if we could add the capability to display buttons as rows rather than columns.

As you can see below, this simple change makes a huge difference in the readability of the UI.

For now, I am adding the invisible brail character (⠀) to the button labels to achieve this. However, this solution is not ideal as it can break depending on the resolution of the display device.

if it looks better to have them stack vertically, let's make that the layout rather than make it an option
