Count me in for the basic scheduled transactions (one off, monthly, 6 months, yearly). I used to have a bill that was charged every 8 weeks, but that went away a while back. I always thought it would be nice to have a few variable options like Once Every XX Days, Once Every XX Weeks, Once Every XX Months. Previous business day would be great, since that's how my paychecks work twice a month... although it's a little more complicated since holidays are taken into account, which can push a transaction back even further. Now that I think about it, I want automatic previous business day bumping, with holiday awareness, localized for each culture.
