I have attached a screen shot of the fibonacci FAN tool that is available from XTick (russian company) their too is great. It has a number of feature that would be nice to have in VT.
1) you can define projections
2) the current fan tool does not have any horizontal reference lines. Make it almost worthless
3) In XTick you can extent the horizontal lines to the right edge of the screen. makes it easy to validate levels.
4) You can also view the level with the price value at a given level.
I have attached a screen shot for you to review. It should give you a better idea of the tools that VT is lacking.
