Feedback Wait until exiting prefab editing to propagate changes

I have UI prefabs that I need to edit from time to time--but in recent Unity versions, the process of doing so has become torturously slow, as the editor will hang for a second or two to propagate changes after every. Single. Little. Change. This interrupts my workflow so frequently and so egregiously that it's turned editing UI prefabs with large numbers of objects into an absurd time sink.

Please, please: make the editor wait until we're actually finished editing a prefab to propagate changes throughout the project!

 

Just look here

 

Oh wow! Thank you, that's helpful. I didn't even notice that thing there!

A suggestion to the Unity devs on behalf of folks (like me) who might not notice that check box: maybe prompt the user to turn off auto-save if they make more than one change to a prefab and propagating changes takes longer than 0.5 seconds. Or even better: propagate prefab changes asynchronously so that workflow is not interrupted regardless!
