Right now MediaViewer's "Open in Media Viewer" button is placed directly below the preview image on file description pages. This needs to be changed!
**Rationale:** File description pages should contain information specific to a file (that's why they //are// called //"file description"// pages). Navigational elements that are not specific to the file should go into one of the designated navigational areas.
Right now (especially when other extensions/gadgets are active on a Wiki) file //description// pages often are structured like this:
"//preview image > button > another button > MediaViewer buttton > button > description//" (find the error...).
Please note that this change was already agreed on by WMF staff back when MediaViewer was first enabled, see
Re-evaluation of the buttons position was promised multiple times by Fabrice Florin, however until today nothing has changed!
