The problem is that:

        almost all of libui is routines for the Wireshark GUI that are toolkit-independent (and, in those cases, end up 
calling routines with a toolkit-independent API but toolkit-dependent implementations);

        most of the rest of libui is code for taps that are implemented in both TShark and Wireshark;

        one remaining routine in libui glues multiple arguments together in a string (used by some programs, including 
but not limited to TShark, to take a bunch of tokens from the command line and make them into a filter string, 
tcpdump-style).

Those should probably be split into at least two separate libraries, possibly more.
