Where you have unfinished or temporary code, you can leave yourself a todo inline. Hammer keeps track of all your @todo tags and displays them in the build output right inside the app.
/* @todo Fix this CSS */
// @todo Fix this javascript
Hammer looks for these tags in your HTML, CSS and Javascript, and shows them in the main window.
This is a great way of keeping track of all your unfinished work and makes sure you never leave one behind.
