In Visual Studio 2013, when comparing files (e.g. TFS source against local) it's possible to:
1 - view files side by side
2 - view all differences in single file (TFS source line appears above new local line for those lines that have changed)
3 - view just TFS source file (highlights lines that have changed, showing original lines)
4 - view just right file (highlights lines that have changed, showing new lines)
Whilst the first option (side-by-side) is very clear, long lines of code require the user to have to horizontally scroll the line, which can be frustrating when one needs to see the whole line.
When performing code reviews, we therefore tend to use option 2 90% of the time, swapping to side-by-side only when there are a large number of code changes.
This request is for an identical feature in KDIFF3.
Thanks
