Oh, you wonderful person, you.
I think I was given source code to a project that will do this last week, but I haven't had the time to boot to Lion and compile it yet.
This is the start of bringing sanity back to the Mac OS. The fact that we had to wait so long, that third parties had to do it and that Apple thinks that scroll elasticity/bouncing on the Mac is a good idea means that someone making the decisions for the GUI for Apple is still sick in the head.
Scroll elasticity on the Mac OS is the Clippy of the Mac world.
I will distribute this to the Xcode lists.
You are now on my Christmas list and in my Will.
If you want a copy of TextEdit without the bouncy, please let me know and I'll build you a copy.
I have downloaded a copy of the WebKit source. I with I had time to make a Safari plugin (or version of Safari) that fixed the window tab order and disabled elasticity and auto quitting.
EDIT: OH, Fofer, this is the compiled version of the code that was sent to me a week or so ago. Much thanks to Thomas Clement for this.
