+1 for this.
Just yesterday when I wanted to close the filters panel I inadvertently clicked restore filters, so I lost all my color groups (as well as the other settings). I wish I could reload a saved preset profile then!
I have a small .md file where I keep a few lines of more or less complex and refined filter options (path, -path, etc.), so I can just copy and paste them as needed. But it would probably be faster and more relevant as loadable presets.
In any case, I find it very useful for color groups, because choosing consistent colors takes time, and being able to save conceptual, thematic or practical palettes would be great.
