Bins is a software that allows you to save your shortcuts. Not only does it allow you to quickly access to your favourite application but it is also possible to save your task bar by using small icons. To organize them, Bins suggest you to sort them by theme and even to create categories if needed. You just have to drag and drop to add an application to a group. Note that when the mouse pointer hovers over a group, this latter appears like a dock on top of all open windows.
