I am looking for some way to set break point in guitracer in some module I use in my base function. At moment I only know the way to set some break point after the guitracer enters the module first time. Is their a more direct way?

The built-in editor can set breakpoints (using Prolog/Break at from the menu). @oskardrums debug adapter for Emacs can do it and you can call set\_breakpoint/4 and friends (see manual). I do not know which other editors support this.
