I very much like the GTK client but there is one thing that bugs me. I frequently need to toggle roads display on/off and the only way I can find is using the mouse, click the menu, open a sub-menu and finally finding one of four options. I'd very much prefer a keyboard shortcut, either for all terrain improvements (individually) or at least for the roads/railroads/...

btw: to me its confusing that hiding roads also hides rivers, I understand them to be means of faster movement, but it still seems counter intuitive to hide them, when hiding roads
