MPalette Pro is a Blender addon from CGoutset for speeding up the shading process. It keeps materials one click away, lets you build a per-file palette or a reusable material library, and assigns them to any object.

Easybackup is a Blender addon from CGoutset that generates backup files in one click, saving the original to a different directory with a specific name while packing all textures and adding date, time, and a custom suffix.
