I currently have a widget switcher (which doesn’t work) and I was wondering if it would be better to just change visibility of widgets based on what button is pressed and how I would go about doing that? I’m not sure if create/destroy would work due to the nature of the widgets. I need to be able to switch between inventory, crafting, stats, map, and journal. 
You could always use a vertical panel with all the widget you want inside that and just change their visibility to Collapsed when not in use.
They’d still ‘exist’, but would not take up and space or render.
