Light js applet using Microsoft's Graph API to retrieve and curate information from MS To Do.
Upon login, it fetches all available lists from your account so that you can select a specific list (or 'All tasks' if desired) and a daterange. This applet will fetch all tasks in the selected list that were finished within the specified date range.
Note: all communication happens between the browser and Microsoft's server, this is just a js app running entirely in the browser.
