Strongly distinguish between resources that are created, deleted, and modified. The deletion notification is fine as-is (Spacelift seems to display a ❌ for each resource), but a few improvements would help:
Use distinct colors for creations, deletions, and modifications (e.g., green, red, orange).
Group and emphasize deleted resources given their importance.
Group and emphasize delete-then-create resources separately. These are dangerous and easily overlooked. In our manual GitHub setup, we colored these red rather than orange (like other updates) specifically because of their impact.
