Feel free to write everything below, and I will transfer them up here in to the main post. This is also an easy way to see what's already been suggested.
1-Full profiles and vwap.... These are coming.
2-Increase the size of the rotation markers.
3-Fixed range profile (with delta)
...An arrow key or whatever that moves the viewable screen to the current time. (Bookmap has what looks like a play button on the screen that does it.)
