Great mod keep it up!!!!!

1. Transitions when you bring up the "wheel" of tools (animations when entering or after leaving tool belt) can sometimes stutter when you have a lot of other HUD elements or are on a machine with lesser framerates. It would be nice if we could disable them in-game somehow.
2. When you bring up the wheel and hover over a tool with the mouse, it would be cool if you could just auto-select that tool you are hovering (without actually clicking it, like in games that do the wheel selector), though this probably should be a default-off in-game toggle so others aren't confused if it changes.
3. In-game documentation "book" (most mods are now having these) or even better "ponder" is becoming a quite cool and popular way to document in-game items. Your mod could become more well-known just by adding either of these.
4. This is kinda opposite of #1: Sound effects (configurable?) and maybe a thick highlight around the selected tool in the wheel, configurable of course.

That's it, those are my suggestions.
Keep up the good work!!!!!
