Thanks to Alex Blewitt's blog post JCrypTool now offers full-screen support on Mac OS X 10.7. Not a perfect solution, since some Eclipse internals are used which create the corresponding Java compiler warnings. But better than no full-screen at all. The visualizations look just great in full-screen! Hopefully Eclipse will provide an official solution for full-screen support with Indigo SR1.
This feature, among others, will be available in our next weekly build and of course the next official release sometime in August 2011.
