Pinned addresses
Pinned and kept tabs remember the page they were pinned on, as in Arc: once you browse away, the row shows a slash and the page you're on, and a click on its icon takes you back. Edit Pinned Page in its menu makes the current page its address, or lets you type one.
Glass in Look
On macOS 26, a space's transparency ends in a bead of Liquid Glass: pull past the end and the window frame turns to glass tinted with the space's color.
Labels' menu
A right click on a label in mail's column offers Mark All as Read, Rename, New Label Inside, Move To, Make a Split of its senders, Hide and Delete, as a folder's does.

Switching spaces
With many tabs, switching spaces starts sliding at once instead of after a pause.
New windows
A new window opens on the screen of the window it came from, a step right of and below it, as macOS does.
Tabs out of a full window
A tab dragged to the edge of a window that fills its screen comes out into a window of its own.
Shortcuts in ⌘T
The chosen row in ⌘T's list keeps its own shortcut at its end, as in Raycast.
Needs you
Mail's Needs you and the new tab's Now leave out cold sales sequences and automated mail.
A kept tab's minus
A kept tab's minus turns into its cross as the tab is put down.
Address over glass
The column's address blurs what shows through it over glass and drawings, so it stays readable.
Quieter new chat
A new chat shows nothing over its field when there is nothing useful to suggest.

Looks live in Spaces
With spaces, each space's look is set on its page in Settings › Spaces; Appearance points there.

Traffic lights
Pointing at the close, minimize or zoom button shows the marks on all three, every time.
Sidebar slides again
The sidebar (⌘S) and the agent's chat column slide with the page again instead of popping in and out.
Tabs across the top
No line before the first tab when nothing is kept, the tab's × matches the icons beside it, and an open folder's name is no longer cut off.
Site icons
Sites that check for bots first, like Dribbble, show their icon instead of a letter.
Bitwarden passkeys on GitHub
A Bitwarden passkey works on a page left open a while: GitHub's Continue with passkey waits for your pick instead of failing at once.
Mail's account chooser
Mail's account chooser opens again after switching spaces.
Mail's list
Mail's list closes up smoothly when an agent archives a mail.
Bookmarks bar switch
The bookmarks bar's switch in Settings brings the bar in and out smoothly, as ⌃⌘B does.
Sidebar over the look card
The sidebar brought out over the page stays out while the look card or a menu is open.
Agent's memory
The line under an agent's chat says what it remembers in words, not markdown.
