In a project, when I click on a task to view it in detail on the right, the task on the left is subtly shaded in a light light light gray.
When I follow a task link and the task opens on the right, I often want to scroll the list of tasks in the project on the left to see other tasks around it to adjust dates, possibly see who else is involved with related tasks, etc.
The light light light gray shading is very difficult to spot.
Could Asana make it pop a bit more?
Also, if a SUB-TASK is presented on the right, I would expect Asana to highlight the PARENT TASK on the left in the project task list view. Maybe the treatment could be slightly different to help indicate the parent-subtask relationship.
