When selecting multiple images for grouping, the only way to group them is by right-clicking one of the images (the one that should be "on top"), then select from the menu Group, then select one of the Group actions. Toolbar buttons for the various grouping actions will make this much easier. It will also enable grouping while in Preview mode, which currently does not support a right-click menu. I suggest the following buttons: * Group selected. * Auto-group selected - opens a drop-down with the various automatic grouping methods. * Ungroup selected. * Remove selected from groups. * Show/Hide group - toggle (so no need for two buttons).
If grouping functions are available in the main item menu, then they can be automatically added to the toolbar with the toolbar editor as well, so I'm closing this bug as a duplicate. Maik *** This bug has been marked as a duplicate of bug 472879 ***
