Follows sunrise and sunset in your time zone, or you pin it to one.

How the theme is chosen.

Automatic
By default, Draftline follows the sun. It works out sunrise and sunset based on your time zone and switches with them, so the writers who drift from afternoon sessions into midnight ones never have to think about it at all.
Fixed
Some authors prefer one theme at all times, and whether that's always light or always dark, we built for that too. Settings has a manual theme selection preference, so you can always use the theme you prefer.
Everything follows
When it switches, everything switches, the page, the manuscript panel, the dashboard, the Read Aloud player. We themed the whole studio, edge to edge, to ensure the entire application is easy on the eyes in any light.
