I have decided to no longer hold on to the source code of Hosts File Editor. I never really intended to make a profit from it so it seemed like the right thing to do.
I have put the source up on GitHub for your downloading pleasure. There have also been some pretty big enhancements to the program that are now in GitHub.
The interface has been pretty well overhauled. More color, shortcut keys, etc. Most of these changes are thanks to Josh Minnie at Nissi Solutions.
More changes are going to be heading to this in time. Mostly fleshing out the unit tests.
