Awesome new features 
I really love that the first version of grouping is released. However, I was hoping that there wasn’t a need to open/close levels to see what’s in a group.
Currently we hacked grouping by using a board view with only 1 column.
Would be awesome if that’s possible in a table since you can then show more helpful information.
In the released version of list grouping, I need to open/close each and every state / assignee / etc. to see what’s in it. That’s not UX friendly in my opinion, especially when there is no expand/collapse all feature.
The benefit of grouping is that you can easily scan the page, based on groups. Like Clickup or other tools have (old screenshot from Google):
In Fibery it feels like relations instead of groups
I also really miss the icons in this setup, especially when you group by state. It gives the workspace just that extra bit of love.
