I think i'll also implement my own session restore since firefox's seem to be pretty out-of-date with what our vision looks like

Will this sync across other devices as well? Or only windows open on the same device?

[mr-cheffy]

Only across windows, not devices

How does this handle multiple windows trying to show the same tab? I'd love for Zen to copy Arc's UX here. Arc does it by showing a greyed out version of the thumbnail (screenshot from the tab in some state) in all unfocused windows and only having it actively rendered in the window that last had focus.

This would be amazing!!!
I've had to entirely avoid workspaces on desktop bc of the lack of sync. I started using them on my laptop tho, and now I realllly want them to be usable on my dual monitor desktop 🙏🏻

Got window initialization and syncing half-done 👍🏽

It's ready when it's ready; as long as there's active development happening in it, it'll arrive eventually.

I was wondering when this pull request is likely to be merged?

It should be the next big feature that'll drop, but between firefox and windows breaking something on every update its getting a bit delayed so people get their bug fixes

(Which btw, @mr-cheffy, thank you so much for keeping working on this despite being pulled away for those things 💚)

Just waiting this feature to turn Zen my principal browser, instead Arc.
