Have different sets of working days for different employees (e.g. part time workers)
Different leave categories, and ability to set them up to not remove days out of the primary leave allowance (e.g. for unpaid holiday)
Leave requests can be approved or rejected by a leave approver
Graphical leave calendar for quick visualisation of people's holidays
Ability to manually adjust people's leave balance and add/remove days from their allowance
