In planner, I would like to see more information without opening the goal. For example, I would like to be able to see the goal's status, template, and plan all at the same time.
Currently, you can only see details about goals if you change the "Color By" display. The following suggestions would make this easier:
Always display the icon associated with the goal template so you can see what kind of template it is.
Always display the (color coded) plan icon so you can see which plan the item was in (including hovering to see the names of the plans)
Always display the colored circle associated with the status.
Or, if not always displayed. Add an option in "customize display" to turn these on.
