Added
- Sidebar see-through (Look, off by default): how much of the desktop shows
through the sidebar and the gaps round the page, a little, some or half; the
page itself stays as it is. Zen's own see-through is one fixed amount, and its
space colour's slider sets how strong the colour is rather than this. On
macOS, and on Windows and Linux where Zen's window can be see-through.
Fixed
- A screenshot's preview (its Retry, Close, Copy and Download) is in Zia's look:
Zia's tiles, Download in Zia's blue, on Zia's card colour. Its styles never
reached it, as it's a page of its own in a dialog, so it kept Firefox's
buttons; Zia now puts them into the preview as it opens.
