This is what I avoided by writing a tree widget for the TUI, I really didn't want to traverse _all_ the hists just to show the ones that appear in the screen.
Isn't there a way to ask GTK to ask a callback to provide a representation for the Nth hist entry, i.e. just the ones it _needs_ to render the screen?
Anyway, great to see this work!
