Now that we have the Ignore White Space option in the diff, an extra useful feature might be "Revert White Space Changes".
In my local changelist I have a bunch of files that are only white space changes so when I diff them with the Ignore option on it says they are identical.
Rather, than go through each file manually and check it would be good if I could right click on the changelist and "Revert white space changes" and get IDEA to do all the work for me!
What do you think? Is anyone else this lazy to like it as a new feature? :)
