When using the fill tool’s various gradient modes, I often find myself choosing a pattern only to find out that it’s unavailable for the gradient mode I want to use. It’s really not handy to have to go over all of them one by one to find out which patterns you can use.
I’d like to see any sort of indication on the pattern selection menu showing you which patterns are available for the currently chosen gradient mode. I believe this would be really easy to implement, and would save a lot of time for the user.
