Let's say a website project gets set back 2 weeks. I don't want to have to manually change all start dates and end dates.
I know that dependencies and sub-tasks solve part of the problem, but sometimes, there are tasks that aren't dependent on (or related to) each other. Ex. Google Analytics config and CDN settings can be done at the same time (they're not "related" to each other).
It'd be awesome if we could reschedule/shift an entire folder/list start and/or due dates back/forward a certain number of days or weeks. That way, we wouldn't have to adjust things manually every time a client delays something ;)
