The first thing coming to mind was when she made a force-field that doubled as an invisibility screen was tricked Terrax into thinking he disintegrated the team.
I forgot the issue, but he blasts each of the members and Sue simultaneously protects them and turns them invisible to make him believe he killed them.
Another similar time was in Marvel Knights when she created a force-field that absorbed and contained ambient light, so that she could use it as a torch.
I'm sure there are other times she's combined both that I can't think of right now, but she's definitely never done something on the scale of a planet before. It's especially impressive for her force-fields which were at most citywide before.
She seems to be naturally reaching the point Johnny was when he became Galactus' herald with her powers back in Waid's run. While that case was a forced evolution, this seems like a more natural growth.
