Libre office impress hide/show slides

Libre office 3.6 features a function witch shows a “quick menu” for hiding/showing slides when dwelling over the slide in lefthand slidemenu. This seem to have been removed in Libre office 4. Why?

The hiding/showing functionality is still be accessible when you right-click on a slide. I guess they removed the quick menu to prevent users from clicking mistakenly. While I was using 3.6, I clicked and cloned/hided slides mistakenly for several times.

I agree with removing it, it was only source of mistakes during my work.
