Choose label column in gallery view


As an app creator, I would like to choose the column used to label my gallery entries. Both deck and table allow column selections; it would be nice to allow it in gallery, too.

In addition I would like to have 2 lines of label (a Primary and a Secondary label) that could be set to any of the table column and to have a Main image parameter to select the column to be used as the gallery image. It would be nice also to choose if the images are rounded or not.

In a summary to have similar features as with the Deck view.
