We're introducing a change to the formatting of the site today. Previously we've tended to split off items from alternate timelines into special "Temporal" sections. However, with the advent of the Kelvin timeline the number of such items has ballooned massively over the last few years. So as of now we're rolling things like alternate timeline ships and people into the main menus of the site, and differentiating them with a new colour. This means the "Ships" menu now contains both the Constitution class from the original series and the Constitution class from the Kelvin timeline, the People menu has both versions of James T. Kirk, and so on. This has the benefit of simplifying the menus somewhat as a side benefit.
The old colour scheme remains in force. So if you see a menu button in orange, it will lead you to a page written from the point of view of the Prime timeline. If you click on a blue button, it will lead you to a page written from the point of view of the real world. And now, if you click on a pink button it will take you to a page written from the point of view of a non-Prime timeline. The same colour scheme applies to buttons within pages, image outlines, etc.
We expect to be tweaking this a little as we deal with any issues we might come across. Let us know if you find any issues!
