Quick and easy squashing

Open two terminal windows:

1. git log --name-only;

2. git rebase -i <SHA>~;

Additional notes:

1. remembering your sha can save you from a bad rebase. 💯

If you screw up badly:

git checkout SHA;
git checkout -b you-recovered-the-branch

2. git status is your friend.
3. create new branches to protect your code.
