For the minimize/maximize windows, you can preface your script with this line:

The split ID will use a 0 instead of a dot, so split 1.1 would look like this:

For restoring windows, you'll have to track the state with the ScriptSettings functions: https://www.displayfusion.com/ScriptedFunctions/Help/#bfs_scriptsettings

For example, you'd have two code-paths in the script, one that minimizes the windows and sets a registry bool to true, and one that restores the windows and sets that registry bool back to false.

Hope that helps!
