Maybe this is the wrong thread but once in a while I stumble across a tool that makes life so much easier that keeping it to myself seems pointless.
If you work with web related code, or conventional code, or even many of the other app formats available then keeping up with what changes and where can be a daunting task.
I found this tool recently that helps me when I compare each successive release of a particular CMS's CSS and HTML to make certain my templates are compatible with each release.
Its FREE and a cool tool for those who have editors that DON'T have this feature. You can compare up to three seperate files for changes and get a visual representation of where those changes or differences reside.
Worth a look;
NO THIS ISN'T MY PRODUCT and NO I DON'T SPAM FORUMS. This is just a friendly "LOOK AT THIS" kind of a tool I found. If you wish to move the thread then I'll understand.
