Option to show "ghost" of previous slide

I was shuffling some items around in a title today and I thought to myself "it would be nice to see a faded out version of the previous page." If you had the option to see the contents of the previous page, it would be fantastic when the time to reposition items on the next page arrived.

For some context... I was quickly putting together more quiz questions. Lectora slaughters fonts and positions when you update the questions (I was switching them from drop-downs to radio buttons) and I wanted it to match the rest of the quiz on other pages. I had to turn on gridlines and do my best attempt. Things are always a few pixels off.

I generally find it difficult to line things up. While we're at it... it would be really cool to be able to line up items based off the positions of other items on the page. Think like Windows Forms Application design... Without it, everything feels a bit sloppy.
