A much more expanded version of the request was discussed in
"Click info on savepoint".
To save you some clicking, here's a summary:
This was a request about clicking once for looking at the status at that current checkpoint, and double-click for restoring.
One problem is that unlike Wonderquest, it is possible to click on lots more stuff in DROD and it will do something. That means that, for example, if you have a clone on the checkpoint and you click on that square, it might not work as what you expected.
A second difference is that clicking in Wonderquest can only restore once, in DROD one can restore more than once on the same checkpoint.
