About this Mod
Change appearance of the box highlighting the block you're looking at

Background
There was an awesome mod called "Custom Block Selection Box" by BeastGamer
But it edits base classes, so it wasn't compatible with so many other mods, it was for Minecraft 1.3.1, and not updated for ages, and also all downloadlinks are broken...
-> It's just OUTDATED
So I made a new one, without any baseclass edited (using MinecraftForge), with an awesome settings screen,
and for the newer Minecraft version (starting with 1.5)!
(And during the time I was gone, shedaniel maintained a fork :P)
I also added some new functions:
- disabled depth buffer
- custom block break animations
(check them out)
And shedaniel added:
- linking of connected blocks (chests, doors, pistons, beds)

How to open settings
(recommended) Using modmenu or Mod Settings
If ModMenu/ModSettings is installed, you can access the config screen from there.
Otherwise, a button will be added in Options > Video Settings
