Sorry, my English is not good. I hope it didn't offend you.

Unify GUI
I hope you can unify the GUI of mod Nature Compass and Explorer's Compass.
The searching bar in Nature Compass is on the left side of the screen but in Explorer's Compss it's in the middle of the screen and darker than the other one.
The scroll bar exists in Explorer's Compss but doesn't in Nature Compass.

GUI Suggestions
When I'm scrolling the list of structures or biomes, the elements in the list will cover the searching bar.
I suggest to put the searching bar above the list or move the searching bar under left buttons.
The elements in the list are so close together that when I select one, it will cover the above one (just a little).
I suggest to add an empty line between two elements.

These two mods are really excellent!
