SCM: Add amend checkbox to commit panel

[dmstern]

For now, we have the opportunity to amend commits via command palette or via git context menu.

It would be great if there were an amend checkbox right beside the commit message box to have this feature integrated in the source control panel.

Thanks for submitting this issue. Please also check if it is already covered by an existing one, like:

• Commit (Amend) loses multiline format in commit message (#40295)

Atom has a nice UI for this.

It's really needed feature. I for example use specific GIT repo where I should to amend my latest commit with automatically generated UID, on first commit, in commit message. Then my changes will follow to same PR. Otherwise if I will lost that UID on second commit (when I execute amend) then the GIT repo will create second PR instead of change previous.
Also WebStorm has this feature. Why don't you consider opportunity to implement this?

On other git editors, the checkbox to amend a commit writes the commit message with previous commit if the field is empty.

There is also the arrow dropdown menu next to the Commit button. It includes Commit, Commit & Sync, and Commit & Push. "Commit Staged (Amend)" could be added to that menu. For that matter, so could "Stash"

"Commit (Amend)" is now available as a secondary action on the "Commit" action button.
