I got addicted to making the patcher full screen and double clicking to lock it back into place, but if you do this in osx it minimizes the whole program.
This next one I'm not sure if it's osx specific or not, but that's where I noticed it. If I make a tabbed group of the patcher and automation windows and then double click on the patcher or automation windows and use the command 5,6,7 buttons to show and hide windows and also double click to shrink back eventually I lose either the patcher or automation windows. I hit the shortcut to bring it back or the tool button or right click and it show up for a second and quickly does the osx shrink animation and goes somewhere unknown.
BTW Zooming in looks really good on osx! :) It makes me think that while it wouldn't be practical, it would look awesome and very organic if we could resize groups of contraptions and nest them inside larger structures. Haha.
