Marcel Taeumel uploaded a new version of Morphic to project The Trunk: http://source.squeak.org/trunk/Morphic-mt.1095.mcz
==================== Summary ====================
Name: Morphic-mt.1095 Author: mt Time: 31 March 2016, 1:04:44.478525 pm UUID: 277ef4bb-1fb5-40a2-b443-1d0555ebc707 Ancestors: Morphic-kfr.1094
Make it possible that new-style balloon morphs can appear also at the morph's center and not only close to the hand position. Also adds the possibility to open multiple balloon morphs at once via subsequent calls to Morph >> #showBalloon.
