I love the idea of "schedules" per channel/context, but the UI is quite tedious and difficult to user. Further, it's buried fairly deep in the settings, which makes me far less likely to use a fairly helpful feature. I'd love it if there was more of a drag and drop style way to set schedules. I'd also love it if there was a better way to access it via the main UI, either from the calendar panel or a more visible channels editor.
