better ponds and springs

there are way too many ponds and holes that form in the natural terrain currently.  (both lava and water ponds) It makes it very difficult to build, travel, and conceptualize builds with these gaps. I think they should be more sparse. This is especially an issue in the plains biome. I think this would be a relatively easy fix in the new update. conversely, maybe these ponds have frogs or special plants like reeds to make them look better.
