There's already the "show more" of CellBrowser / CellTree and text in the SimplePager.
We shipped our first milestone Monday and our customer already asked us to translate that "show more", so it's going to be an issue soon (we have the whole dataset ready though, so it's rather a bug in our code as we're not setting the visible range to show the whole dataset, similar to how AbstractHasData#setRowData(List) works) -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
