On Android the app along with the tracked entires it overlays the local calendars. It’s useful to compare the day’s plan and how the time spent. The durations are especially useful to see how much time was spent on each task at a glance. Right now, the app only shows the durations for entries that are longer may be due to screen space limitation. On tablets and foldable phones there is lot of horizontal space that could be used to show the durations right next to the titles even if the size of the event is small. Please fix this. On Mac app it shows the durations right next to the titles even for small events.
