For the longest time, I couldn't figure out why some of the waypoint names in my GSAK database were showing up in bold text:
I finally realized that it wasn't due to a bug in the program, but rather another built in filtering feature. By default, GSAK highlights geocache names that have child waypoints in bold text. You can turn off this filter, or create your own font-altering filters, using the "Highlight..." command under the "Waypoint" menu:
The above example shows the filter that causes the geocaches with child waypoints to be highlighted in bold text. It just uses an "Mfilter" statement to set the search criteria. Just for fun, I created another highlight control that lists the Last GPX Date in red font for any waypoint that hasn't been updated in more than 30 days using this MFilter statement: $d_LastGPXDate < $_Today - 30.
You can set up to 20 different, and simultaneous, waypoint highlight filters. As if the standard GSAK filtering tools weren't powerful enough, the Waypoint/Highlight controls provide additional filtering options.
Oh, and by the way, a new version of GSAK (7.5.2 Build 27) was released this week that includes a number of bug fixes and minor enhancements.
