If you’ve tried sorting your shape keys, you know full well how impossible that is in the default state of Blender.
But don’t be discouraged as Shape Key Collections gives forth that functionality for structure and stability in the form of folders!
So put your beloved shape keys in any folder you’d like, or their subfolder. Name them, sort them, find practicality and order.

Split Keys
Combine up to 3 shape keys in one place, displaying each value. The advantage of this being you can group related shape keys together, allowing for improved management and simplified control over your mesh. Imagine, for example, you have two eyebrows, left would be shape key 1, right: 2, and both eyebrows together: shape key 3. Your shape keys are now synergized for operational effectiveness.
