 ==== Keeping track ====
-==== Color control ====
+The thumbnail widget has a special button that allows you to track your progress throughout a slide:
+{{ ::viewport_tracking.png?direct&200 |}}
+Once enabled, a gray overlay covers your slide's thumbnail, with pieces of it gradually disappearing, as you start navigating your side. The zoomlevel at which you inspect a specific region of interest, influences the outline color in the tracking screen.
+{{ :viewport_tracking2.png?direct&400 |}}
+This kind of tracking is instantaneous and ad-hoc. When you close the viewport, it disappears, and its history is not logged. If you're interested in tracking viewing operations over time and across your use population, you should have a look at the [[heatmap]] functionality instead.
+==== Color correction ====
+The default PMA.UI representation in PMA.core shows a color correction widget in the top-right corner of the viewport.
+{{ ::viewport_color_correction.png?direct&400 |}}
+Use it to control brightness, contrast, and gamma correction.
