Moving from Arc
Since 
Arc stopped adding new features, many people have moved to Chrome, Dia or Edge. Lumno brings several of Arc's interactions to these browsers: the command bar, switching between recent tabs, restoring pinned tabs after a restart, and automatic picture-in-picture for videos.
Lumno is an independent open-source project and is not affiliated with Arc or The Browser Company.

How to switch
- Install Lumno: from the Chrome Web Store for Chrome and Dia, or from Edge Add-ons for Edge.
- Open
chrome://extensions/shortcutsand set "Open command bar" to ⌘CtrlT, the same key as in Arc and
Zen. See Keyboard shortcuts. - Press ⌘CtrlT and try searching your tabs, bookmarks and history.
- To move between your last few pages, press ⌥AltQ to open the recent tab switcher.
If the shortcut doesn't work in Dia, change its scope from "In Dia" to "Global" on the extensions page.
Arc features Lumno can't provide
A sidebar, Spaces and split view depend on the browser itself, so an extension can't add them. If you rely on them, try Zen Browser, a Firefox-based browser similar to Arc, or 
Vivaldi, which also has a sidebar, workspaces and split view. For more, see What Lumno can't do.
