On the edit page for a component (or the page to add a new component), the only available button is "Confirm".

To a user who is not familiar with the tool and wishes to go back to the index page, it may not be intuitive to have to click on "WatchTranslations" in the header to return and not save their edit, especially as many people (myself included!) feel uncomfortable pressing the back button in our browser when filling out a form.

For these reasons, I think it would be nice to have a 'Cancel' button alongside the 'Confirm' button on the edit page.
