plone.app.mosaic provides a "Format" menu for tile where you configure e.g. the text alignment of the content within a tile. What is the particular usecase for that. In case of a RichText tile I would align the text according to my needs using the TinyMCE controls of the tile. Why is this needed? I understand that you need sometimes a formatting options for the row e.g. for the background color but the formatting of individual tiles should be left to the individual editing option of a particular tile, or?
