Terrain - Buttons Instead of Dropdown Menu

[Monkey Frog Studio]

For the terrain editor, I think it would be nicer and faster to work with if we had a set of buttons for sculpt, paint, smooth, flatten, and vegetation instead of a dropdown selection menu. To switch from one tool to another, you need to first click to expose the dropdown menu, then click on the tool you want, If we had 5 buttons, all the end-user would have to do is click the button (one action instead of two). 

Thanks.
