The userway widget when enabled has its button hidden away behind the World Anvil Logo on the left side. Additionally once it is opened with CTRL+K on the desktop it is covered by all the widgets. When opened with Athena/Image Manager active, it doesnt appear or appears behind them. And lastely when enabling Contrast option to dark/light the the menu is still there but becomes invisible, but that might be a userway issue.
1. enable userway widget.
2. check all the elements
3. use the button that says Contrast a few times
According to a user the invisibility issue doesn't happen for them in a private window so that might be caused by an extension. I have uBlock Origin
