Any valid URL, File, or other script functionality that would normally be accepted in an <a href=...></a> tag is allowed.
An HTML value will be used to as the HTML content for a modal pop-up window that will appear on-top of the application when the user clicks on the application title.
Supplying NULL will disable the title link functionality.

log_level

Designating the log level to use for the user log as 'DEBUG','INFO', 'WARN' or 'ERROR' (default = 'DEBUG')

app_version

Character string designating the application version (default = '1.0.0')

It uses waiter (see https://waiter.john-coene.com/#/).
Pass a list like list(html = spin_1(), color = "#333e48") to
configure waiterShowOnLoad (refer to the package help for all styles).

announcements_file

. Use load_announcements to configure announcement.
