Construction acceleration

Hi, I come here to suggest a slight change in the place where the point of paying constructions gems, there if you click once she speeds up and ready, and that ends that often impairs some players who just clicking it by accident. I know a lot of players who already did it and lost much more than 1000 gems.
I would like to propose to you in place on the construction, when click it to open a dialog box asking if that’s what the player wants to, just like when you’re selling an item in the throne room and there pops up a small window asking if is that even if the player wants. So would avoid many losses of gems by players.
