Feedback Please make the humanoid animation animating process more easy for Unity

Some people like to animate their players of characters or whatever inside unity ....I would like to make my character animations inside unity and I want them as humanoid clips ....Animating the muscles of the player its very hard because you have to move another muscle to rotate the leg ,another muscle to strech the leg and more .We would like to see new and easier ways to animate humanoid animations inside unity .
Inform me if you will make an update for this thing so I can Update to the newest version.

Thanks a lot
