Sometimes super simple tasks work best when performed using super simple applications. List making might be one of them.
Preflight is a free list-making app that's about as simple as they come. Type your list item in the "new item" box and hit return. Job done. If you want to delete an item from your list, select it and hit backspace. You can rearrange your list through drag-and-drop. The beauty of Preflight is that it's quick to load, create a list and does what it needs to do.
