Tweaking custom biomes is cumbersome. Each time you load a scenario to edit its biome, the biome editor reverts to default ground brushes rather than retaining those from the prior edit.
Also, it would be an improvement to have eight brushes per row rather than six. This would mean each biome would occupy one row. All "Steep 1" brushes would be in the first column, and so on.
