This mod makes you place blocks a lot faster. You can open a menu (O by default), you can configure how fast you want to place blocks. Then by pressing "V" (by default, you can change that) you will place blocks really quickly.

When toggled on you can see mobs/player with invis potion effect.

When creating a new world you have a new button, there you can configure the randomness of your survival world!

When you take screenshots, you can view them ingame, with coordinates saved.
