Another strange suggestion ...

It would be very cool if we had the option to make text invisible, for spoilers and the like. If the font colour is set the same as the background colour, you have to select the invisible bit to see the contents, if you see what I mean ...

Although, having it work the same way as emphasis would be very annoying, as you'd normally use it for a whole paragraph ...
