It feels cleaner and more streamlined overall.
One thing that feels harder now is accessing agents saved in Favorites. Previously, the large rectangular cards were very easy to click on desktop. Now, you need to click the relatively small Dust icon and agent name within the “New conversation” area, which feels less discoverable and less convenient. I imagine most users access Dust primarily from desktop rather than mobile, so the larger click targets were useful.
I also like the quick-fire call-to-action buttons. It would be great if these could be customised per user, unless that option already exists and I have just missed it.
