It is needed to evaluate and design highlighting and "iconizing" of task nodes. Decide what should be highlighted and iconized.
- task status - new/modified/unsubmitted/conflict - last two are ignored
- scheduling - do we want to highlight close due dates or missed due dates
- scheduling - do we want to add any icons related to scheduling
- task priority -
- task type - probably not, recently added info in tooltip should be enough
- task status - highlight or icon, or both?
