I finally managed to make one of the best button dynamics -- the one which Google uses... In which, when you press down, a fluid fills up the button smoothly and when you release, the fluid fades. It's different from @SpartanDav's version, as I made it MYSELF. I admit I took help for the size change (of the fluid thingy), but for the smoothness and where the fluid fills up from, those were my work. If you want to use this in your projects, add the function scripts, or maybe improve this and kindly give credit to me somewhere in it. Thank you!
