GuidScreener is a custom GUID/UUID generator for Windows and Linux (freeware), that generates RFC 4122 format GUIDs from the system generator or a high quality random number generator and allows you to preset selected digits to generate a more easily recognisable ID, for example:
C0FFEE42-31C2-478A-A6A3-97F1EBCA6256
This facility can also be used to create groups of GUIDs that will appear adjacent in a sorted list.
Help information is built in (Main menu Help/Help or F1 key).
It should run on Mac OS X El Capitan (version 10.11) and later versions, in addition to the previously released versions for Windows and Linux distros.
Tested on Mac OS X El Capitan (version 10.11) and macOS Sierra (version 10.12).
Created using wxWidgets 3.0.2 and the Code::Blocks IDE.
