For non-trivial reviews, when there are files with several changes, I tend to do the following in Git:

1. Create local branch for the pr to review
2. Squash if necessary to get everything in the one commit
3. Soft reset, so all the changes are modifications in the working tree
4. Go thru the modificiations "in situ" so to speak, so I get the entire context, with changes marked in the IDE, instead of just a few lines on either side.

Just curious if this is "a bit weird", or something others do as well?

(ed: as others mentioned, a squash-merge and reset, or reset back without squashing, is the same, so step 2 isn't necessary:))
