I would love to be able to lock a component to its set grid area.
When i have multiple components and the browser starts to get sluggish i end up accidently moving components and I'm constantly having to use the history tool to restore the accidental moves. A button to lock a component to its assigned grid area would be perfect.
I run into this all the time too 
This is a great feature request, I’ll make sure to keep you updated on it!
I'd get a lot out of this feature too! I'd use it to lock the position of the tabbed container that holds all of my components. Without being able to lock the tabbed container, I can't select multiple components within it without painstakingly clicking on each one.
