@c600g I agree with you. Comparing block by block is friendly for reading, while comparing line by line is convenient for editing. These two comparing methods are both useful.


The expected implementation maybe like this:

Add a button to the upper-right corner of the compare pane. This button is responsible for switching between block-by-block and line-by-line comparing methods. The default comparing method is the block-by-block one. Click the button once, the comparing method is switched to line-by-line. Click the button again, the comparing method is switched back to block-by-block.
