Since the version 1.6.4 of Minecraft, we could not do secret rooms, but really you can do many more things than secret rooms.
Secret Rooms 1.14.4, 1.12.2 and 1.11.2 allows to do lots of things realted to hidding, for example we can create blocks for our houses which will work as a glass only from inside the house and will look as a wall from the outside.
Another of the highlights of this mod is that lets to make invisible levers or pressure plates invisible to bring down our friends. Although the mod offers many more useful things, either to hide things from us or to hide ourselves. To see all this things I recommend taking a look at the video:
