Published theme

Stillfox

A quiet theme inspired by Linear and Apple Notes. No borders: the toolbar, tab list and page melt into one surface that takes on each site's colour. Tabs on the left or on top, an optional hover sidebar, a sun and moon dark/light button, and an ultrawide-friendly toolbar. Inter included.
