WHAT DO YOU RECOMMEND
In the new Library design, I think there should be a separation between the different columns to communicate clearly to which Relation an “Install(ed)” button belongs
HOW COULD IT BE DONE
Add a faint vertical divider as I’ve added below (only red to clearly show what I mean).
REAL WORLD USE CASES
When you have a large screen with many columns, it might be less obvious whether the install button belongs to the Relation on the left of it, or the one on the right (which is closer).
RECOMMENDED ALTERNATIVES
Alternatively, make all Relation buttons equal in size and either stop the Relation button just before the Install button
Or group the two buttons with a faint line
ADDITIONAL CONTEXT
Same goes for Types.
