The KeepChatGPT userscript is useful, but visually rather intrusive. It's placed at the front and top of the page, topped by a rather unattractive design badge. The whole emblem is only used to access the preferences and has no other function. All of this could have been neatly tucked away behind the 'three dot' menu.
For instance, another equally handy userscript, the ChatGPT Exporter, does this elegantly, so it doesn't disturb anyone. It's positioned appropriately, mirroring the original style, in the bottom left corner of the page.
So I've decided to implement a single CSS style for KeepChatGPT that removes this ugliness, leaving only a small hoverable area to access the necessary options from this script. It's just a CSS style that removes the huge and ugly banner.
