IFD540/440 Touch Screen GPS/NAV/COM : Wishlist for the next IFD software release

You can configure a datablock to display the VOR, Distace, Radial to the tuned and identified VOR in the NAV radio.  That would have given you the information you requested, updated real time.  Another way is to use the range rings on the MFD to estimate distance which should be accurate enough for ATC position reporting (remember time/speed/distance calcuations?).  A third way, although not an IFD, could be a two finger tap in Foreflight to measure the distance from your position to the VOR on the sectional.
