From Daylite 3.1 and onwards, you have contextual menus which operate per object type. For example, if you control-click(right-click) on a Task, you may get options such as "Subtask for...", "Link Task", "Status", etc.

You also have the ability to change what is in any given contextual menu.

Go to the Daylite preferences (Daylite -> Preferences...). Click on the "Contextual Menus" preference pane.

Here you will see a row of buttons along the top, corresponding to each type of object for which you are able to define a contextual menu. For instance, if you click on the "Organization" button, you will see below on the left, a list of menu items that can be added to the contextual menu for Organizations. On the right is what the current menu for Organizations will look like. Drag items from the left table to the right table in order to add them.

Delete items but selecting an item in the right table and hitting the "delete" key.

Change the order of the items in the menu by dragging.

You can also add a separator item to the menu. This can help to keep your menus easy to read and grouped logically. When you are done, be sure to close the preferences, and the menus should now be updated.
