Tasks and groupings in resource board and the gantt chart are more easily collapsed and indented than they are in project plans, timesheet lookup and other lookups.
Project plans or lookups are not grouped and indented enough to make them easier to look through.
Having an option to collapse/expand would also help.
Can the functionality in the resource board and gantt chart be replicated?
Makes it easier to identify what you are looking for and easier to read.
