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.)
Re: profiles.....Perhaps a fixed range volume profile tool would be useful? Especially one that can generate a VP using delta. TradingView has a decent fixed range VP and a delta feature, but the delta calculation is typically way off.
