Biome titles can only be anchored to the top_center and to the top_left corner of the screen. Maybe you could consider enabling bottom_left, bottom_right and top_right as well. I'm currently using top_left corner and like my biome titles to be shown on the bottom left corner but if I change GUI size, the biome title also changes position (y-level). Having a native "bottom_left" option would be nice!

Agreed! Somewhat tempted to make a pull request that adds this...
