Hello,

I tried to make an aquarium with some substrate going to the surface (actually trying to make a cascade but then I discovered that there is no pump) but the landscaping height tool only allows going up to maybe 30cm. It would be nice if we could raise it to the surface or higher (a simple limit would be a height above the tank equal to the tank height).

Also, in the case of deep subtrate to create anoxic subtrate, it would be nice to be able to have layers. Maybe find a way to stack subtrate by thickness... For instance we could have layer 1 which is like now (minus the height issue) and then a + button to add another layer with the lanscaping controls same as now but applying only to the selected layer.
