I use overview grid rather often, so the current (~0.5s) transition is rather slow as to me. It would be nice if we would be able to set this timing at least through the defaults. I personally would like to set it to zero.
Ok, I’m shorthanded and didn’t see the “Zoom to overview grid animation” option, which could be used to set the None to disable the transition at all.
However, it would be nice if this option was mentioned at the docs for Overview Grid 
Right, we should mention it, thanks.
