The new Windows desktop version of Roster Wizard is well underway. I am using the BeeWare Toga library which is a Python native, OS native, cross platform GUI toolkit. See: https://toga.readthedocs.io/en/latest/.
This version will be useful for people who prepare rosters but do not have the support of an IT department. It will be quick and simple to install. See latest code here: https://github.com/galojix/roster-wizard-desktop.
