Clicking the upper right avatar picture brings up the theme settings. In its top row, there are three icons: day and night view and then there’s an icon with an eye. I failed to figure out what effect it should have.
The entry about the theme settings in the Wiki mentions the day and night view, yet not the function of the eye icon.
I hope you don’t mind my suggesting to add it.
Please let me know, if this is not the right forum category for this kind of topic.
Thanks for letting us know about this gap in our documentation, we’ll get that fixed up.
In the meantime, the eye is our accessibility option which utilises colour blind friendly alternatives (which I personally think are better even for those with good vision)
