Support for more subtitle styles

I aggree : please fix this asap it is a easy update for you: there should be an option to apply all the frame and slide to same shifted position

kindly improve or add new subtitle animation style like popping effect, each word come one by one popping animation, and when someone shift subtitle to some position there should be an option to apply all the frame and slide to same shifted position. you can refer CapCut subtitle animation and effect slide move. It will help more high quality and high engaging attention-grabbing video.
