Feature Description

Export data to Excel function.

Problem / Motivation

I’m using the widget for daily work tracking and want to keep track of tasks along a longer period, along with the ability to visualize that data in Excel.

Add button that exports the data in an Excel worksheet, listing tasks, time spent and % spent (numericl and graphical).
