A long anticipated feature! Hope they add this soon

This is an absolute necessity. I've made changes by mistake countless times on both iOS and Mac

Yes, please!

I've accidentally dragged things without realising it. But even worse, I sometimes delete notes/events and immediately regret it. So some sort of undo would be fantastic :-)

Undo button +1. I feel this is important as it will provide peace of mind when using Morgen extensively. For example, in Apple Calendar I use the undo button a lot when I reorganise my schedule quickly. I drag an event to see if it fits around my schedule. If it doesn't, I press undo.

+1 on what David said, Ive dragged events accidentally multiple times and although I can put them back, sometimes I have events with very specific times and I generally don't remember when exactly they were scheduled.

Today, I dragged an event by mistake. And undo button is very important as I could not remember when the event actually started.

I feel that this is especially important as there is no confirmation for dragging events, and that is too easy to do by accident
