Can I have another copy of SimpleTODO that uses a second list?
Yes. All you need to do is copy the shortcut to SimpleTODO, and then edit it (Right-click and ‘Properties’ on Windows). In the box where the path to the target executable file is specified (e.g. ‘C:\Program Files\SimpleTODO\stodo.exe’) add ‘ -file C:\mytodolist’ on the end of the path, where ‘C:\mytodolist’ is the path to your list. So, for example, the entire target path would be: “C:\Program Files\SimpleTODO\stodo.exe” -file C:\mytodolist When you launch the new shortcut, SimpleTODO will open a new todolist at the location specified.
