Improve the look of tasks view by removing duplicates and adding icons

Under profile > tasks...the task list has duplicate data. Suggested improvements:

1. the @ mention AND assignee column. Wouldn't it be enough to display in assignee column?
2. the date appears as a part of the tasks description AND in the due date column. Keep just the due date column.
3. add icons in from of the pages
4. add (maybe optional?) column for space in which this page > task is found

make all columns sortable! That way user can start working on task by due date, or by project (space / or page depending on the particular wiki organization)
