> Added the ability to set the default state for new scenes.
> Added the option to display the actual object instead of parented objects (grayed out in the outliner) when selecting an object with parents.
> Experimentally supported expanding bones in pose mode.

https://blendermarket.com/products/shape-key-collections

Organizing shape keys used to be a nightmare because you couldn't give them a folder structure in native Blender.  This is where Shape Key Collections saves the day and allows for full control over your shape keys. Bring structure to the chaos, a folder structure, that is.  With this new management system you can rename and organize which shape keys go in which folder and subfolder, including the benefit of subfolders for full tidiness and ease of use.

https://blendermarket.com/products/better-fbx-importer--exporter

Blender is lack of native FBX support, when we import some older and newer FBX files, it often fails.

So I made a better FBX importer and exporter with official FBX SDK from scratch.

The add-on is compatible with all FBX versions, from ASCII to binary, from FBX 5.3 to FBX 2020.

I have tested the importer and exporter with about one hundred commercial FBX files which made by 3d digital artists in 3ds Max, Maya or Cinema 4D, the add-on can import and export these FBX files successfully.

The exported FBX and DAE files have been verified in Unity Engine 2019, Unreal Engine 4/5 and Godot Engine v3.2 with no issues.
