Both the gradient tool and the pattern too have a specialized tool option 
docker for their handling.

How about a styles tool as working title.

I like the idea as it enables both types of working. 

I thing it would be good to combine the two tools. There are some points which 
I think should be discussed before starting to work on the topic:

- Would the tool either work on a gradient or pattern depending on what is 
used on a shape?
- What whould happen if there is a gradient forground and a pattern background 
would it be possible to edit both at the same time?
- How would you handle the different tool options that are shown when the 
gradient tool/pattern tool is selected?

That is already implemented like that.
