I also missed the ability to read the data from plots.  Here
is a cheap way to read mouse clicks

	data = Table[RandomReal[], {10}];

	res = {};

	Dynamic[res]

	EventHandler[
	 ListPlot[data], {"MouseUp" :> AppendTo[res,
MousePosition["Graphics"]]}
	]

Enter each line in a different cell of the notebook.

Now, whenever you release the mouse button inside the plot
area the output cell of Dynamic[res] will be updated with
the position of the click.
