I love the 'every month on the 10th' syntax for repeat tasks. It would be great if this functionality could be enhanced further as some of our tasks need to happen each month but the date may move around slightly.
E.g.
3rd Monday of the month
17th working day (how to define working day.. weekends/Bank hols)
2nd Tuesday after First Friday of the month
Last Wednesday of the Month
20th or First working day after

Any thoughts?
