[Pharo-project] About the merging tool and "affordance"

Hi all With Stef today, we kept scratching our head about how the new merging tool works. Sure it looks cool, but it is not 100% intuitive. A few suggestions: - above the compare panels, show which version is displayed (or which one is the current, which one is the incoming) - the direction of the arrow left/right, depending on whether we keep the current or the incoming, seems wrong. Inverse it? -- Simon
