Is your feature request related to a problem? Please describe.

For anybody less familiar with python, or less comfortable with computers in general a software update will be a pain as it is now.

Describe the solution you'd like

Add an update button to the version number. Can be restricted to the one-click installer version.

Additional context

Minimally it would be good to highlight whether a new version is available and provide a step by step guide to an update.
