I have the todo list and the event list above. When the todo list shows new items, the window goes below the event list and I need to move it everytime. Until I remember today the Sidebar window. But, to show only the two together, I added a visible="0" property on the calendar window (is this a good idea for an option?

).
After that, I notice that the buttons didn't appear. Finally, I found the problem: The todo list was updated (I don't know when), but not the "copy" in the Sidebar. It says:
<image element="bitmap.todo.item" origin="TOP-LEFT" x="0" y="0" />
But bitmap.todo.item has 3 frames. This need to be a button to mark as completed, need action, etc.
