Feature Request : Gradient Meshes, and additional things related

I'm aware that gradient meshes have been implemented into Inkscape .92 regardless of Operating System being used. I was thinking of some few features in mind.

1) Gradient mesh through stroke
2) Generating gradient mesh from path
3) Being able to paint gradient mesh much in the same way you do with raster program
4) Being able to make tangent lines actually tangent to another line.

Those are some few feature I have in mind.
