I love Compare It! I happened to install a new version of my favorite text editor UltraEdit and I noticed that the compare tool that they sell does something neat. From the shell window you can select the first file you want to compare and then the second and third before the program opens.
It is hard to explain without pictures but I was thinking it could be a nice new feature for the wonderful Compare It! They have a demo version, it is called "Ultra Compare".
How is the three way merge coming along, I can imagine it is super hard as you have said in your blog. I would not need that often but I was just curious. I am trying to get my company to purchase CI.
Thanks!
