Template for a workflow to track tasks that follow steps. It can alert on due and expired steps per each task, while also navigating to alerted cells with a single click. It also demonstrates the use of conditional rules and ARRAYFORMULA.
Example: this spreadsheet implements a workflow to track states (columns) of a list of people (rows) by coloring cells that need attention.
To use the spreadsheet, make a copy of the spreadsheet first, then refresh the spreadsheet and use the newly installed "System" menu.
