Viewer panel consist of one or more viewports organized in grid and toolbar underneath it (only in single-slide mode). Currently selected slide is highlighted with the blue dashed border [#1 on a picture #1]. When user adds new viewer panel its grid has only 1 column and 1 row, so it's single cell grid. When changing grid size application will always ask what to do with slides that were already loaded into grid - whether application should preserve it or clear all.

Toolbar is placed underneath the viewer [#2 on picture #1] Toolbar consists of (left to the right): 
  - Flip horizontally
  - Flip vertically
  - Rotate counter-clockwise 90 degrees
  - Rotate clockwise 90 degrees
  - Rotate 180 degrees
  - Previous slide
  - Next slide
  - Magnification buttons

PIMSLS allows to load multiple slides into the grid in addition to opening multiple viewer panels with grid inside. Each slide position could be changed using [i] [#1 on picture #2] button on top of viewport - it's required to drag and drop that [i] handle to the desired position - it could be either another cell, tray or new viewer panel. In addition Column/row of grid also could change it's position - there is a handle [#2, #3, #4, #5 on picture #2] near each row or column that could be drag and dropped to the required position.
