Fold a space
Click a space's name above its tabs to fold its kept tabs and folders away, or bring them back, as in Arc. Its ••• or a right click opens the space's menu.
Agents send what you asked
An agent can send a mail from Yab's mail page when you asked for exactly that one, after you say yes on a card showing who it goes to, the subject and the words.
Check for Updates
The Yab menu has Check for Updates…, and Restart to Update once an update is ready.

Same marks for errors
Developer Tools' errors list marks Errors and Warnings with the same ⊗ and ⚠ as Console, instead of colored dots.
Updates within the hour
Yab looks for updates every hour instead of once a day, and an urgent fix restarts Yab by itself once you have been away for ten minutes, your tabs back as after ⌘Q.
Any setting by asking
⌘T and ⌘J can change any setting tasks can change, like the search engine or peek, not only the theme, sidebar, tabs, fonts, zoom, mail and bookmarks.
A kept tab's minus
A kept tab shows a minus under the pointer, as Arc's pinned tabs do: it puts the tab down and keeps it. Put down, its cross takes it out of your kept tabs.
Files by their path
A path on your Mac typed or pasted in the field, like ~/Downloads/report.pdf, opens the file instead of searching for it.
Smoother with sync on
With sync on, picking a tab or an agent's step no longer counts everything sync holds on the main thread, which could hold the window for seconds on a busy Mac.

Frozen tabs
When WebKit's drawing process stops answering, Yab restarts it by itself and your pages draw again, where a tab you picked kept showing the one before and pages never loaded.
⌥⌫ in the field
⌥⌫ in the field takes off the address it was completing, then the word before the cursor, as in Chrome.
Devices that answer only https
A router's or phone's page that answers only over https opens, where typing its address gave "The site won't accept connections".
