Actually, on APRSIS32, you can just right click on a station and it start tracking center on him. Either way, the client also adds a Friend Range filter when you're tracking someone using the normally configured range. That way if s/he/it travels beyond your normal circle, you'll still get the updates as well as stations around them.

If you add b/CALL* filters to your Add Filter string (space delimited where CALL is the prefix of the call you want to track or the entire callsign without the *), the client will reverse-video those stations in the scrolling station window.

For instance, here's the filter I run on KJ4ERJ-AP:

I was tracking a friends progress on his flight in his airplane.
That AF3K in my buddy filter is a cool boat that I was tracking as it went down the Intercoastal Waterway on the Atlantic side of Florida. Really a cool boat. We had dinner with the owners when they were here after I tracked them down the coast from Jacksonville. See their boat at:

Is there a way to save the tracking log so that I can forward it to him as reference for his speed & path ?
Unfortunately no. But that's a really good idea! The program actually buffers tracks for ALL stations which is why you see the lines all the time and get dots for the recent positions of the centered station. Maybe just a new popup menu option to "Save Track" that's only there if there's a sufficiently interesting number of points. I'll add that to the list right after I learn how to write out GPX files of your own track! It'd be a simple extension of that one.

PS. Sneak peek for those that read this far. I'm planning to support "track in separate window" in some future release of the Win32 client. The additional window would be only a map and scale bar, but will otherwise behave like the main window. Then you can keep one window zoomed out for the local APRS picture while putting up a "picture in picture" (if you position the windows correctly) of the details of one or more interesting stations.
