The image in the mask or use the background as a reference to use Gaussian blur

[idea] The image in the mask or use the background as a reference to use Gaussian blur
===About why I want to add this function, it is also available on other design apps. It is very useful for UI designers.

Gaussian blur in the mask can simulate the display effect of ground glass
as shown in the following steps
-1-
Let’s create the underlying graphics first
And add the image that needs to create a mask


-2-
Create a mask

-3-
Find “Gaussian Blur” on the bottom quick toolbar or sidebar Find “Gaussian Blur” on the bottom quick toolbar or sidebar

-4-
Then u can change the Gaussian blur of the image in the mask

!!! But I think it is more necessary to “use the background as the object of Gaussian blur in the mask”. Similar to iOS, as shown in the figure
Because it suddenly occurred to me that it is more practical to use the background as the object of Gaussian blur in the mask


It is equivalent to using mask for Gaussian blur in the selected drawing with all layers after this layer as reference

All the layers after this layer are used as a reference, and the mask is used for Gaussian blur in the selected drawing, as long as you click a button to complete the function
