Now that you created all the screenshots for your Todos, it might be helpful to create a workflow that will quickly get rid of all the screenshots you now have in your photos. I call it the screenshot triage workflow. This is a very simple workflow that has just 4 actions. The first action is Get Latest Screenshots. You will want to set the number of screenshots that you have from your most recent "How-to". Then we need to add Repeat with Each so that the next action Delete Photos will loop through and delete the screenshots for the specific number of screenshots chosen in the action. That's it! A very simple workflow to help you keep your photo library and screenshot folder clean.
