Long time user, but I would love to see a fortnight / 2-week view on the calendar week view, as I often need to move and swap roster events around within a given fortnightly pay cycle and this would make things so much simpler to see the fortnight in one view.
Complementing this would be an option to demark week cycles, ie fortnightly / monthly pay cycles, on the Month view. This could be simple alternate shading with a definable start day, bearing in mind that pay cycles (or whatever you’re tracking) doesn’t necessarily start on a Monday.
