Great arc circle direct navigation. Could be as simple as a heading bug on the HSI or as advanced as a line in the sky with desired altitude to boot!

When traveling east or west between two points on the same latitude the shortest distance between those two points is NOT along the line of latitude but along a Great arc. Traveling along a great arc (other than a line of longitude) requires a constantly changing heading.

An indication as simple as an automatic moving colored heading bug which indicates the direction of the great arc circle between the current location (updated continuously) and the destination point.

This has the potential to save a lot of gas and time and wind drift is automatically corrected.
 
SkyView already does great circle flight planning. When you ask for a direct route between two points, the path is a great circle. Our map is a bit different than others- we use a spherical projection, not flat, so the line on the screen is always straight, but it is the shortest distance over the sphere.

As you fly this course, the HSI will actually tell you to slowly turn against magnetic heading to get you to fly the arc.
 
The PFD shows you indicated airspeed, pressure altitude, and magnetic heading.

The map shows you ground speed, GPS altitude, and ground track.

They're only ever the same on a standard day with no wind at sea level.

Then there's a feature for you to fix, now, before you release the new version of software.

If something is displaying *ground speed*, make it say that, or "GS".  Similary, heading != track, so make something showing a ground track say "Track".  Same for GPS vs. Pressure Altitude...make the GPS one say "GPS ALT".

That's a simple fix, and avoids ANY confusion.

(BTW, is your GPS altitude MSL, HAE or HAG?)
