-    - Avoided adding new methods. Only deleted from here.
-  'packages/editor-ui/src/mixins/**':
-    - Avoided adding new mixins (use composables instead). Only removed code from here.

-    - Avoided adding code here. Only refactored to make it smaller.
-  'packages/editor-ui/src/hooks/**':
-    - Avoided adding new hooks. Only refactored to move hooks to relevant store instead.

-  'cypress/e2e/**':
-    - Avoided chaining commands more than two or three times (to avoid flakiness because only last one will be retried).
-    - Spoofed endpoints that are not critical for the test (to avoid flakiness).
-    - Picked most efficient path to start the test (for example skipped account setup and starting at /workflow/new for a canvas test).
-    - Avoided adding waits on time (use request intercepts instead).
-    - Ensured each spec does not depend on any another spec to pass.
