It is possible to display only those frames that are defined on a given page using the TeX/LaTeX->Flow Frames->Display Page dialog box. You can select to display those frames that are defined on all pages or just those that are defined on odd or even pages or you can specify a particular page number by selecting the Page radio button and entering the relevant page number in the text field. If you specify "0", only those frames that have the None page setting will be displayed. Note that objects that have not been assigned flowframe data will always be displayed. The title bar will indicate how many objects have been hidden.
It's generally best to apply transformations or edits with the All Pages setting on. If you move an object when the verso (even) page is displayed, the object's recto position will be moved by the same amount. The only way to have a different verso position is to apply an even page shift in the TeX/LaTeX->Flow Frames->Set Frame dialog (or to apply an even page shift to the typeblock).
