Hello friends, 

I am working on a new extension. 

It requires Inkscape 1.1+  ( Will not work on versions prior to this )

It's designed to produce effects across basic objects. 

At the moment it does Colour gradients across objects.

I've uploaded my first draft of it at:

https://gitlab.com/inklinea/Spacey/

It appears under the extensions menu 'AAA' - just because that appears at the top for testing :)

** It can crash Inkscape to the desktop if lots of objects are used, so please be aware of this **

Thanks

I've updated it to add: 

nth child colouring

basic csv colour list import in hex, rgb and css name

I've updated the gitlab version ( not on the Inkscape website ) to include text labelling of objects:
