Only restore programs that are not running?

Is your feature request related to a problem? Please describe.
It can be a bit annoying that all programs are restored regardless of whether they are already open or not. It would be more convenient to have only missing programs restored.

Describe the solution you'd like

1. Get list of programs to restore
2. Get open windows
3. Get commands for open windows
4. Loop through open programs
   • Use list.remove() to delete matching programs from list of programs to restore

This would change existing behaviour though, so it might be best to add a flag to make it optional. I would appreciate feedback on this.

#64 makes it so only missing programs are restored, but I'll leave this issue here for a while in case anyone has any problems. Wouldn't want to break anyone's workflow 😉
