I would like to see the following features added to the diff tool.
1. Incorporate something like the DiffFilePlugin:
To allow two files in the project to be 'diff'ed, or using the commander
2. Extend the existing diff viewer to support easier merging of diffs.
I love the existing diff viewer, it would be great if it supported easy
merging of diffs. How this might work would be that you could click on a
particular diff line or section, and be given the ability to move it
over into the other file. This would be immensely useful.
Anyway, just my 2c, I will file a tracker request, but thought I'd bring
it out to the list for any additional feedback.
