allow timed comments to slowing fly from left to right of the window

hi Viki:

I used to be a customer of bilibili.com. I am attracted to viki because your content are more complete, but i don't like the way viki implement its timed comments.

Can you make it slowly fly from left to right, like bilibili.com did? It is easier and faster for people to read the comments while they are moving. You can read multiple timed comments on the screen at the same time while watching the shows.

Thanks!
