Spring RTS Engine

I would like the in game option of showing the height map to be altered.
instead of showing lines of height which arent always obvious,it should,IMO show different shades of a single color based on height or assign different colors and shades to different altitudes.

for example:the lower 20% can be shades of red than another 20% shades of purple etc..Or just a single color with many different tones.

A map-editing gadget would probably work best for the implementation of this.
edit: misread the post...a heightmap-editing gadget would still be awesome

F1 view shows even small roughness, you can see the large differences without assistance anyway.

IMo what i suggested would make height differances much clearer and faster to understand.
