UtilityKit

Mostly static utility classes that are used across multiple projects. This seems like a better place for them than in individual Gists.

SerializationUtil

Wrapper for dealing with BinaryFormatter in a way that works on AOT/IL2CPP and regular platforms

ObjectInspector

Generic Object Editor that provides the default inspector along with some additional goodies like Vector3 collection editing in the scene view and clickable buttons to call methods

StripGeneratedSolutionSettings

Fixes the cruft that Unity injects into MonoDevelop solution files

MathHelpers

Various mathy helpers that I find myself using often

ConstantsGeneratorKit

Generates constant classes for Layers, Resources, Scenes, Tags and SortingLayers. No more naked strings all over the place! It has it's own README markdown file with more information.
