GCode Visualiser - showing preview of current layer

I like to see how far the current layer has left to go so, I've made a couple of tweaks to add an additional option to show the full current layer as its being printed (similar to how the next/previous layer preview looks - i.e. slightly faded with the print progressed being overlayed darker).

Is there any interested in me submitting a pull request or has this already been discussed and shot down (the changes were fairly simple and straightforward so I was a little suprised that this hasn't been requested/done already)?
