Hi, We do have the ability to lock events on our list of functionality to add in the future. If you move an event by accident, then undo should be able to reverse this, are you finding that it isn't working for you? Jess
I want to second this! I have historical and celestial events that are actual and need to be locked. I work around it by positioning other events relative to these locked events, but it would be FABULOUS if we could LOCK the event and it has a different shade outline so we can see it's locked.
