Unfortunately plank is not suitable for heavy users because it is simply too simple and the developers do not have any plans to enhance it in the future. The most significant lack is that of the previews, see: https://github.com/ricotz/plank/pull/3.
Are there any plans to move away from plank or substantially improving this fork?
