Feature branch commit amend by default

When I work on a feature branch, I always amend a single commit:

- I don't want to have to deal with commit messages each time I push a small change to my feature branch

- In the end, when I merge my feature branch, all commits are squashed to a single one, so the commit messages are lost

Each time I commit, I need to check the "amend" checkbox in the commit dialog.

I would like to have an option "Always amend commit on a feature branch", so this checkbox would always be checked.

It could be turned off by default.

Thank you, I love your product :)
