To adjust the speed:

* Select the "Presentation" tab in the left pane
* Right-click on the mark at the end of the transition to change
* Set "Time" to the number of seconds you want the transition to take,
  or "*" plus a factor to set based on the automatic speed (e.g. "*2.5"
  or "*.333").

It's already possible to "pause for N":

* "Mark" twice for the view you want to pause on
* Select the "Presentation" tab in the left pane
* Right-click on the second mark at the pause location to edit it
* Set "Time" to the number of seconds you want to pause there for

Indeed people didn't seem to really take to the feature and I've not
needed to give a caving talk myself for ages so it's not seen any
real updates for a long time (only keeping it working despite many
FFmpeg API changes).
