Two observations: <ul> <li>I noted that while I am creating a line, the toolbar has some issue in the drawing: see the different vertical tints of green in the attached screenshot. It happens when there is a #redrawNeeded message sent to one specific morph underneath. </li> </ul> <img moz-do-not-send="false" src="cid:part1.4A54A35D.ACBA0849@drgeo.eu" alt="" width="413" height="607"> <ul> <li>Balloon appears behind the morph. The difficulties are in the details! So the balloon should always be the top level, then you want the morph responding true to wantsToBeOnTop to stick to position two. Or may be balloon morph on position zero and wantsToBeOnTop number one. Something like that.</li> </ul> <img moz-do-not-send="false" src="cid:part2.31735B41.93A96D27@drgeo.eu" alt="" width="472" height="336"> Thanks!

It is a first sketch, but it seems to work. All you need to do is `aMorph wantsToBeOnTop: true`. Note that when you pick a morph with the hand, you are effectively removing it from the world, so while it is being taken with the hand it will appear above the "top" morphs. When you drop it, it will go behind them. We could have several layers, if that is needed. Try it and tell if it works for your needs.
