Ohh, I was surprised it's not implemented yet. :)
That feature is very convenient in React dev tools.

In case anyone is in need for this feature like right now,

I created a library that does this:

vue-devtool-flash-updates

If it's ever needed, I would be more than happy to port it to this library.

For those interested, I created a little plugin in my own application if ever someone wants to make library or something (I myself do not have time to maintain / contribute library) cf https://github.com/blaadje/Todolist/pull/103/files

PS: cc @yuichkun I did canvas drawing instead of adding class to elements in order to avoid issues (inspired by react-devtools)
