Back to where the link came from

A tab opened by a link, a page’s window.open or a link in a Peek remembers the tab it came from. Back walks the page’s own history first; with nothing behind it, Back closes the tab and shows the tab it came from again, as in Arc. Pinned tabs and split panes keep Back for their own history.

Drag the sidebar’s edge down to 164 pt, as in Arc. Below 212 pt the header turns into Arc’s narrow one, with ← → and a ••• popover for Reload and Toggle Sidebar. A slow drag snaps to 228 pt, where four favorites fit, with a tick; drag under 82 pt and the sidebar hides, with Arc’s tip about ⌘S the first time.

With the sidebar hidden, the pointer now waits a tenth of a second at the window’s edge before the sidebar comes out, so brushing the edge no longer flickers it. It springs in on Arc’s curve with Arc’s tight soft shadow, and stays out until the pointer is well past it. Favorite icons are 16 pt, the URL pill and the favorite tiles share Arc’s hover, and section titles use Arc’s ink.

The + at the bottom of the sidebar opens Arc’s creation menu, New Space, New Folder, New Easel, New Boost, New Split and New Tab, in the space’s own colours, with the + turning into × while it’s open.

A tab dropped on a folder goes in at the top and the folder stays shut, as in Arc; the tab you were on peeks out under it. Folders no longer spring open while you hover with a tab.

Double-click a favorite that has wandered away from its pinned page and it goes back there, the same as Back to Pinned Page in its menu. A single click still just opens it.

Right-click a download, in the tray or on Library ▸ Downloads, for Arc’s menu: Open, Copy, Show in Finder, Cancel Download, Hide from Cra and Move to Trash, plus Pause and Resume. The bin over the Library button carries a progress ring while downloads run, and quitting asks Arc’s “Downloads in progress” first.

A link’s right-click menu has Arc’s single “Open Link in New Tab”, which opens the tab behind the page you’re reading, as Arc does. Settings ▸ Tabs has a switch if you’d rather go to the new tab. The menu’s labels now come from Chromium in your language, and the image search names your search engine.

File ▸ Share… opens the Mac’s share menu (AirDrop, Mail, Messages, Notes…) for the page in front. The File menu now has Arc’s five sections, New Space… heads the Spaces menu and New Folder… moved to Tabs, where Arc keeps them.

The command bar has Arc’s sizes: a 64 pt search row, rows on a 50 pt pitch and “Search or Enter URL…”. The selected row and the info badge take the space’s colours on Arc’s neutral grey panel.

Settings ▸ General ▸ App Icon has a fourth icon, Violet: Arc’s deep violet tile with the ribbons in warm, magenta, orchid and blue-violet, and the edge in the colour of Arc’s rim. The picker’s tiles are bigger and sharper on 1x displays.

In Air Traffic Control, a route that opens in a Little Window can now name its space: the page opens in that space’s profile, signed in where that space is, and ⌘O sends it there.
